374144 - Location and status of combo box lists mis-reported in MSAA.

Status: RESOLVED INCOMPLETE

(Thunderbird :: Message Compose Window, defect)

Description

[Rick]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.2) Gecko/20070225 Firefox/2.0.0.2 (Swiftfox)
Build Identifier: version 3 alpha 1 (20070315) -- http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/2007-03-15-03-trunk/thunderbird-3.0a1.en-US.win32.zip

All the lists within combo boxes in the mail composition window  are reported with state visible and locations that are wholly or partly outside the Thunderbird mail composition window.  For example, the list within the list item that signifies To, CC, etc.  First, the list can not be seen on screen (when the combo box is not open), yet its status is reported as visible.  Second, that list's location has a Y coordinate that is 250 pixels less than that of the list itself.  In some cases, certain assistive technology would incorrectly report the presence -- and location -- of those lists.  

Reproducible: Always

Steps to Reproduce:
1.  Select an email composition window with AccExplorer.
2.  Turn highlighting on (the Object -> HIghlight menu in AccExplorer)
3.  Browse the tree to any combo box and observe the list inside it.
Actual Results:  
Blue overlay rectangle from AccExplorer appears above the mail composition window, or partially overlapping its upper region.

Expected Results:  
Lists would not be visible when combo box is not open.

Using default themes and settings.

There were several changes to the APIs since this bug was filed. @Reporter: Could you check with a current nightly if you still get these wrong offsets?
