📝 WalkthroughWalkthroughThe picker now shares value-ID helpers, excludes selected items from search results, coordinates pending selections and focus, handles failed searches, and improves chip removal.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The picker changes can still emit duplicate or undefined selections, allow a just-selected item to be selected again in asynchronous control flows, and surface failed searches as unhandled rejections.

Report the timeout in pollUntil.
pollUntil returns silently when the deadline passes. The failure then surfaces as an unrelated assertion error further down the test. Accept an optional description and throw when the condition is still unmet, so a flaky wait is distinguishable from a real behavior regression.

Merge the two chip-removal helpers.
removeFirstChipByMouse and removeFirstChip share every line except removeButton.focus(). Use one helper with a flag.

`render` returned a bare array of two vdom nodes, which the reconciler matches positionally. `<Host>` is what the rest of the library uses, and adds no element of its own, so the shadow root is unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`getValueId`, `hasPickableItems` and a new `getChipId` are pure functions with no business being members of the component. Moving them to `picker-helpers.ts` lets them be unit tested without waiting out the 300ms search debounce, and puts the "a chip id is the value id as a string" rule in one place instead of two. Not a pure move in one respect: `getValueId` now returns `undefined` where the old `!!value` guard returned `null`, so an item with `value: null` gets the chip id `"undefined"` instead of `"null"`. Both are degenerate inputs, and every id comparison goes through this helper. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A `multiple` picker is supposed to drop already picked items from its results, but the filter compared by reference and `limel-list` emits a copy of the picked item, so it never matched. A picked item stayed in the dropdown and could be picked twice, producing two chips with the same id that were then removed together. Matching is by value id now. Items with no value id have nothing to match on and are kept, so picking one does not hide the rest. This changes the dropdown for every `multiple` consumer, not only those that filter `allItems` themselves: a searcher can no longer force an already picked item to be shown. `getDropdownContent` also asks `hasPickableItems`, since the filter can now leave a result holding nothing but headers. A section whose items are all picked still keeps its header — telling that from the "Results matching" banner needs a change to the shared separator type. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Since 39.27.0 (53d6c95) a `multiple` picker kept the typed query after a pick, leaving the dropdown filtered by a query the user had already acted on. That is gone rather than made configurable: a pick ends the search session, clears the query and repopulates the defaults, as before 39.27.0. Removing a chip or clearing all now does the same, where it used to reset only the internal `textValue` and leave the chip-set showing the typed text. Both paths search immediately, before the consumer can have echoed the new `value` back, so the picker remembers the value it just emitted and builds on and filters against that until `value` catches up. Otherwise the picked item would be offered again, the removed one filtered out, and a second pick made before a slow consumer answered would drop the first. Every path that ends a search session releases the remembered value, so a consumer that declines the change is not left with an item filtered out and no chip to explain it — within a session, though, a decline and a slow answer are the same thing to the picker, and it bets on the slow answer. The default searcher now excludes picked items before truncating to its 20-item cap, which the exclusion would otherwise spend on items already picked — a picker with 100 items and 20 picked showed an empty dropdown. The refresh is also skipped when the removal moved focus out of the input, and a keyboard pick no longer restores focus twice, which used to start a redundant search for the same query.

A rejected `searcher` promise skipped the `clearTimeout` and the `handleSearchResult` below it, so the loading spinner stayed up until a later search happened to succeed. A failed search now leads where an empty result does: `loading` settles and the "no matching results" message shows. Only the awaited call sits in the `try`, so a throw from inside the picker is not blamed on the searcher. The rejection is logged and not re-thrown, so a failing searcher no longer produces an unhandled rejection either — which is how the other nine places in this repo that catch an error behave. The cost is that an error reporter hooking `onunhandledrejection` sees nothing; a developer reading the console does. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
When a chip was removed, the picker rebuilt the value by looking each remaining chip up in `value` by its stringified chip id. Ids are not unique — items sharing a value id, or having none, share a chip id — so with three items where two of them collide, removing the third left the lookup matching the first collider twice: it was emitted duplicated and the second one was lost. A chip already carries the item it was made from, so there is nothing to look up. Mapping through `chip.value` keeps every remaining item, once, in order, and cannot produce `undefined`. Single-select is untouched; it emits `null`. Chips that share an id are still removed as a group by `limel-chip-set`, which filters on the id. That is its own bug, and needs a decision about items the consumer gave no id. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

limel-listemits a copy, so it stopped matching in 2019. A picked item stayed in the dropdown and could be picked twice.valueright after asking the consumer to change it, so a consumer slower than a local round trip lost picks, or had a just-removed item filtered straight back out.searcherleft the loading spinner up until a later search happened to succeed.Backward compatibility
No API change:
etc/lime-elements.api.mdis identical tomain, no prop is added, removed or retyped, and the new helper module is internal.Summary by CodeRabbit
