58990 - A way to get blank lines in threadPane (edge case)

Status: RESOLVED FIXED

(Core :: XUL, defect, P3)

Description

[John Morrison]

I've already shown this to hyatt, but wanted to note it here (but the 
description is brief). 

1) go to a threadPane
2) scroll down to very bottom
3) slowly, pixel-by-pixel, lowere the splitter
4) at the moment when the next row is about to be "pulled down" into the new
   top row, a little whiteness shows in the gap
5) stop right there
6) now click above the scrollbar to page up

Results: threadPane is blank

Note: users will not typically hit this is normal usage, it's just something 
to investigate. 

hyatt also noticed this: at the first downward movement of the tree, the 
Subject column will shift down 1 or 2px relative to the other cells in the row.

cc: esther for mailnews just fyi (by the way, are you the right person for 
threadPane?)
