44055 - Submenus of autoscrolling menus not positioned correctly.

Status: VERIFIED DUPLICATE of bug 57951

(Core :: XUL, defect, P3)

Description

[John Morrison]

Overview Description:

  For subfolders of an autoscrolling menu (e.g., the bookmarks menu),
  as you move further down the list, subfolders in the menu will popup
  in the wrong location
  
  About 40 menuitems down the list, the popup appears ~100px higher
  than it's parent menuitem; about 70+ menuitems down the list, the
  popup may not appear (win95) or may appear onscreen at (+0,+0).
 
  The same bookmarks file appears correctly in the bookmarks sidebar 
  item, or in the bookmark manager. 

Steps to Reproduce:

1) replace your bookmarks.html with the attachment. [The attachment has 
   about 100 fictitious bookmarks, and three subfolders of 10 bookmarks
   each, appended to the default Netscape commercial bookmarks.

2) start mozilla; open the bookmarks menu item.

3) scroll down to "Subfolder B" and note the position of the popup
   scroll down to "Subfolder C" and note the position of the popup
   scroll down to "Subfolder D" and note the position of the popup

Actual Results:
  "Subfolder B" -- position is correct (same vertical position as 
                   its parent)
  "Subfolder C" -- win32 -- about 100px higher on the page than parent
                -- linux -- about  70px higher on the page than parent
                -- mac   -- seems to get this right (it would, wouldn't it)
  "Subfolder C" -- win32 -- does not appear
                -- linux -- appears at (+0,+0) on the screen
                -- mac   -- seems to get this right (it would, wouldn't it)

Expected Results: popup should be level with parent menuitem

Reproducibility: always (but exact positions seem to vary, and may depend on 
                 monitor size and, perhaps, 'line-height:')

per evaughan, actually a structural thing. Adding an attachment to show
what it looks like.

Attachment: popup submenu positioned above its "natural" location.
