requesting blocking, so this doesn't drop off the radar.

This does not block bug 474056 as it concerns window previews and not tab previews.

Sucks, but doesn't block. (It's also not clear to me if this exists in 3.6 as well, but it seems like it should.)

Issue is also present when starting Firefox in a resized window.

Steps to reproduce:
1. Start Firefox in resized window
2. Open several tabs
3. Maximize window
4. Preview in taskbar

Actual results:
 - the active tab has the thumbnail corresponding to maximized window, while the others have the thumbnails from when the window was resized (see screenshot 2)
 
Expected results:
 - all the previewed thumbnails have same size 

When window is resized should the previews in taskbar be also resized?
