If you have zoomed into a page at least by one level with the volume keys on your N900 device and switch from landscape mode to the portrait mode and back again, the tab sidebar is always shown.
1. Open https://litmus.mozilla.org
2. Press the Vol+ button to zoom in
3. Switch to portrait mode
4. Switch back to landscape mode
After step 4 the tab sidebar will always be displayed.
That a general resize problem. I can see that on desktop too just by resizing my window from normal to maximize.

The attached patch is mostly a workaround, I think the right fix involved adding a MozBeforeResize event to the platform.
I am not like the patch that much. It seems like too much of a workaround. I don't think I'd want to take it for Fennec 1.1 in any case.
Another step to reproduce the bug is:
* launch Fennec on about:home
* double click on the fennec/firefox logo
* go to portrait
* go back to landscape
This happen only on trunk, not 1.9.2. This won't block 1.1.
Removing "qablocker" since this is not a Fennec 1.1 issue

I can't reproduce this bug anymore. Can anyone else? Note: zooming is busted for about:home, so you need to use content pages.
WFM now too.
