Whenever an item is removed using the Tab Switcher, the list of matches
is automatically updated, which can lead to the order of the elements
being updated and changing in comparison to what the user was previously
seeing. Unfortunately this can lead to a situation where the selected
index, since it wasn't being updated, would end up in a different item
than the one that was actually active in the pane.
This Pull Request updates the handling of the `PaneEvent::RemovedItem`
event so that the `TabSwitcherDelegate.selected_index` field is
automatically updated to match the pane's new active item.
Seeing as this is being updated, the
`test_close_preserves_selected_position` test is also removed, as it no
longer makes sense with the current implementation. I believe a better
user experience would be to actually not update the order of the
matches, simply removing the ones that no longer exist, and keep the
selected index position, but will tackle that in a different Pull
Request.
Closes#44005
Release Notes:
- Fixed a bug with the tab switcher where, after closing a tab, the
selected entry would not match the pane's active item
