1868094 - When navigating by keyboard in the folder pane, the selected row should always be visible

Status: RESOLVED FIXED

(Thunderbird :: Folder and Message Lists, defect)

Description

[Hartmut Welpmann [:welpy-cw]]

Steps to reproduce:

1. Make sure the folder pane header is shown and that the folder pane splitter's scrollbar is accessible.
2. Press [End] to go to the last row.
3. Use the up arrow key multiple times to go up.

Actual results:

When navigating beyond the top visible row, the newly selected row stays hidden behind the folder pane header.

Expected result:

The selected row should be scrolled into view.

Just to bring this to the bug here, we think the correct fix for this bug would be to change what scrolls in the folder pane to only be the actual folders list without the folder pane header. That way scrolling things to be visible will work correctly reliably. This might still need some JS changes, but the big change is having a new scrolling context that doesn't include the header.
