💡 What is the current behavior?

ix-popover uses an external trigger. While the popover is open, focus often moves into the panel, so native :hover / :focus on the trigger is gone. For ix-button / ix-icon-button triggers, the host falls back to Default chrome even though the overlay stays open. ARIA (aria-expanded, etc.) was already updated on the trigger; the Active look was not.

GitHub Issue Number: #1402 (EIX-151)

🆕 What is the new behavior?

Ownership split (important):

  • ix-popover adds/removes the host class active on the external trigger while the popover is open / closed (and clears it on trigger unbind). This is only applied when the trigger is ix-button or ix-icon-button.
  • The trigger element is responsible for rendering Active correctly. ix-button / ix-icon-button already style :host(.active) via btn-active-look. Popover does not own button CSS and does not remap tokens on the trigger.
  • Plain HTML (or other) triggers are unchanged: popover does not toggle active on them, and they have no IX Active tokens.

Other notes:

  • Existing trigger ARIA updates are unchanged; active is toggled alongside them.
  • Visual popover baselines recreated; e2e opens via showPopover(), asserts trigger active, moves the pointer off the trigger before the shot.

🏁 Checklist

A pull request can only be merged if all of these conditions are met (where applicable):

  • 🦮 Accessibility (a11y) features were implemented — ARIA for expanded state already existed; no new a11y API
  • 🗺️ Internationalization (i18n) - no hard coded strings — N/A
  • 📲 Responsiveness - components handle viewport changes and content overflow gracefully — N/A
  • 📕 Add or update a Storybook story — N/A (no new variant)
  • 📄 Documentation was reviewed/updated siemens/ix-docsN/A unless trigger/Active usage is documented
  • 🧪 Unit tests were added/updated and pass (pnpm test) — N/A (look covered by visual regression; no class-name CT)
  • 📸 Visual regression tests were added/updated and pass (Guide)
  • 🧐 Static code analysis passes (pnpm lint)
  • 🏗️ Successful compilation (pnpm build, changes pushed)

👨‍💻 Help & support

Manual check (react-test-app): /preview/popover — open the popover, move the pointer off the Open IxButton, confirm Active chrome stays; close and confirm it clears.

Summary by CodeRabbit

  • Bug Fixes
    • Popover triggers now retain their active appearance while the popover is open.
    • Active styling is correctly removed when the popover closes or is no longer expanded.
  • Tests
    • Improved popover interaction checks to verify visibility and active trigger states reliably.

Review Change Stack

📝 Walkthrough

Walkthrough

Popover triggers for ix-button and ix-icon-button now receive the active class while open. Component and visual tests verify active-state transitions. A patch changeset records the fix.

Changes

Popover trigger active state

Layer / File(s) Summary
Update popover trigger state
packages/core/src/components/popover/popover.tsx
Popover trigger detection uses a dedicated helper. The active class follows the popover’s expanded state and clears with the ARIA attributes.
Validate trigger state transitions
packages/core/src/components/popover/test/popover.ct.ts
Tests cover accessibility, opening, closing, trigger removal, and trigger reassignment for button triggers.
Validate visual popover state
testing/visual-testing/tests/popover/popover.e2e.ts, .changeset/popover-trigger-open-active.md
Visual tests verify shown, visible, and active states without fixed delays. The changeset declares a patch release for @siemens/ix.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 1586d

The change keeps supported popover button triggers visually active while open, but current tests do not fully verify hover-trigger activation, icon-button support, or cleanup on close/unbind, and fixed waits may make visual checks timing-sensitive. The PR is mergeable with explicit owner awareness of these bounded follow-ups.

close, trigger clearing, and trigger changes. In the visual popover test, retain
the screenshot while replacing both fixed page.waitForTimeout(300) calls with

configuration to include the required brand theme projects alongside the
existing classic light and dark projects.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert the active class for the hover-trigger path.

Lines 73-78 verify that the popover opens and its dialog is visible. They do not verify that the hover trigger has the active host class. A regression can therefore preserve the visible popover and fail the new trigger-state contract.

Add an assertion for trigger after the popover opens. If the test moves the pointer away before its screenshot, assert the class again after that movement.
