1865548 - Collapsing a thread with selections may not set currentIndex correctly

Status: RESOLVED FIXED

(Thunderbird :: Folder and Message Lists, defect)

Description

[Hartmut Welpmann [:welpy-cw]]

Steps to reproduce:

1. Enter a threaded view.
2. Select the first and at least one other message of an expanded thread, making sure that the last single selected message (current index as indicated by the dotted border) was not the root message.
3. Collapse the thread
4. Press up/down arrow key.

Actual result:

The view scrolls all the way to the top and the first/second row is selected.

Expected result:

The row immediately above/below the collapsed one is selected.

This is also the cause of gDBView.hdrForFirstSelectedMessage behaving incorrectly, as reported in bug 1864339.

FYI if this is wanted on nightly for a day or two before beta, then this will make 121.0b6 next week, and then 115.6.0 in two weeks.

Not a 115 regression, so opting to hold this to next week's beta.
