Comment (by cypherpunks):

 Tested with slowdown box, screen size: 1024x768, two desktop pannels top
 and bottom, avail size in result is 1024x706.
 On initial resize (window.mozInnerScreenY - window.screenY) is zero,
 diff_height counted as 82, so delta_fix is 41, then max dimension for
 inner size counted as 1024x583, requested (rounded) 1000x500.
 Resize on MutationObserver: (window.mozInnerScreenY - window.screenY) is
 22, so delta_fix is 23, then max dimension for inner size is 1024x601,
 requested (rounded) 1000x600.

 Window on initial resize is smaller by height, but no about:tor page
 rendered. It even visible how toolbars appended one by one. In result all
 resizing looks like process of creating window and not like sudden resize
 of window.

 Is it what you observes or something else?
