When a tx is pending, once it's removed from the mempool, we keep it in cache until it's confirmed to have a smooth transition. Most of the time it's perfectly fine, but some time some tx can be invalid and they will just be removed from the mempool and never be confirmed. Then the page will still show the pending tx and while receiving 404 from the backend. It's a bit confusing as we are showing a tx, but also showing a 404 error in a snack bar.
