1864911 - List pane position is lost/reset after returning from quick search

Status: NEW

(Thunderbird :: Folder and Message Lists, defect)

Description

[thedonpedro]

Steps to reproduce:

Using keyboard navigation in TB v115.4.3 (64-bit) on Windows 10:

1. Opened the last mail for reading in the mail list pane (=list bottom). Message row was selected (had visible background highlight in the list pane).
2. Pressed Ctrl+Shift+K and ran a quick search in the message list
3. Didn't open any of the results
4. Emptied quick search field to get back the entire list
5. Used F6 to switch focus from the quick search field to the message list

Actual results:

The focus moved to the message list as expected, but the message selection jumped at the very top of the message list.

Expected results:

The message selection should be restored in this case to the message that was selected before running quick search. This feature worked before Supernova.

The above steps work also if there are no results for the quick search (which may be a very frequent use case).
