93966 - Tree in filters dialog redraws strangely when enabling/disabling filters

Status: VERIFIED DUPLICATE of bug 76164

(MailNews Core :: Filters, defect)

Description

[Simon Fraser [no longer active]]

The tree widget in the filters dialog in mailnews shows a very weird
reflow/redraw phenomenon when you click the enable/disable icon for a row. To repro:

1. Open the message filters dialog, with enough filters to cause the list to scroll.
2. Scroll down in the list by a screenful. Click on one of the rows to select a
filter.
3. Click on the green star thing to toggle the enable/disable state of a filter.

Note that we seem to nuke the entire tree, and re-add all the rows, which causes
 lots of screen redraws. This is repeatable.

It doesn't happen every time you toggle the enable state of a filter. It seems
to be caused by a combination of having a row selected, and being scrolled down
from the top of the list.
