Using lightweight themes causes the tab bar to move down 16px
Using lightweight themes causes the tab bar to be pushed down 16px. I know the cause and will have a patch up shortly. Also going to test if this is an issue on all platforms, or just OS X.
This also happens with TB 24. This is onlyvisible by applying the LW-theme. After restart with the LW-theme the margin-bottom is correctly on -6px. I suppose at TB start without LW-theme the titlebar is hidden and the margin calculation in http://mxr.mozilla.org/comm-central/source/mail/base/content/msgMail3PaneWindow.js#1666 can't calculate the correct margin. Applying then a LW-theme bring then the incorrect margin-bottom. After restart with LW-theme the titlebar is not hidden and the calculation can work correctly.
Richard pretty much had it right, except we want the margin-bottom to be 0px, not -6px. In fact, why this whole margin-manipulation was ever added is beyond me. That is for drawing the tabs in the titlebar, which we aren't doing yet. Probably some mistake when draw in titlebar was brought over to TB for OS X. Anyway, this patch fixes the issue by completely removing this margin-bottom modification. Mike, could you take a few minutes to review this?

Comment on attachment 771684 [details] [diff] [review] Fix. This will break on Windows draw in titlebar. The gap above the tabs has to be 16px (for this is the calculation). Maybe it's better to set in messenger.css on #titlebar a margin-bottom: 0px !important. When draw in titlebar comes to OS X then this can be removed and the calculation is working correct also under OS X.

Well, I really would have preferred to use #ifdefs to avoid CSS overrides, but it seems #ifdefs can't be nested in js files. Therefore, I went ahead and just did the CSS override. Richard, now you can review this. :)
