strange transparent areas in firefox caused by xul


wi=window.open();
window.fullScreen=true;
alert("reload");
wi.close();

when opened as the first tab (no other tabs present) and then just reloaded 
causes the following weird effect:

part of what should be firefox window is transparent and if
the content is desktop its items are visible and clickable.

part of the xul is visible or semi visible (font with
transparent background).

the bug is in both trunk and 2.0 on linux, macosx seems
safe. trunk may need several reloads.

this allows tricking the user into dragging desktop items in
the location bar and probably in other areas.

not sure if this is exploitable, but consider it quite
anomalous.

strange blinking behaviour in  icewm, works fine in gnome & kde

Is this still an issue in current trunk build?

Comment 3

[georgi - hopefully not receiving bugspam]

this seems fix on current trunk.

though the testcase gives strange errors:

Security Error: Content at chrome://global/content/bindings/preferences.xml may not load data from http://localhost:8080/trans2.xul.

Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMXULElement.boxObject]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: chrome://browser/content/tabbrowser.xml :: _notifyBackgroundTab :: line 2693"  data: no]

###!!! ASSERTION: Adding child where we already have a child?  This will likely misbehave: 'Error', file /opt/joro/firefox-cvs/mozilla/docshell/shistory/src/nsSHEntry.cpp, line 595

I'll mark fixed.  1.8.x release drivers should figure out if they can, or want to pick up the fix.
