I'm wondering why animated gif are paused when a file dialog shows up, for instance when :
-I right clic -> save link/picture as ...
-File -> save page as...

In fact the problem seems to happen every time another window take the focus :
-every file dialog (open, save, 
-options window
-print window

But it does NOT happen (good!) with :
-page-settings (good translation?)
-import/export
-toolbar modification
-bookmar windows
-downloads
-modules
But every gif is frozen when i drag this windows...

Reproducible: Always

Steps to Reproduce:
1.go to a website with at least one animated gif on the page
2.open a file dialog for example
3.
Actual Results:  
look at the animated gif : paused !

Expected Results:  
Play the animated gif

Probably a dupe of bug 311718.

Unconfirmed (works for me) on Linux (Mandriva 2009) with Minefield 3.2a1pre (Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2a1pre) Gecko/20090306 Minefield/3.2a1pre). With both right-click /"save image" and file/"save as", this animated GIF continues to loop whilst the dialog takes focus.

Confirmed on Windows 7 Pro x64 w/ latest nightly of Minefield (build 20100211050928). Latest Chrome and IE versions on the same OS/PC do not exhibit this behavior.

Doesn't happen on latest Nightly, and probably hasn't happened since at least Firefox Quantum.
