Created attachment 580655 [details] [diff] [review] patch Steps to reproduce: 1. Open XUL Fennec in landscape mode on a Honeycomb tablet. 2. If the tab sidebar is not visible, drag or tap to show it. 3. Drag the sidebar to hide it. 4. Tap the tabs button in the toolbar to show the sidebar. Actual results: The tab sidebar appears, but the browser and actionbar do not resize so they are pushed off the edge of the screen. This is a regression from bug 692357. It happens because TabletSidebar.grab() tells the browser sizing code to ignore the the sidebar, but ungrab() does not always tell it to stop ignoring. This one-line change to TabletSidebar.hide() ensures that we stop ignoring the sidebar no matter which code path we take in ungrab().
Comment on attachment 580655 [details] [diff] [review] patch Requesting approval for Aurora 10. This is a one-line, mobile-only fix for a user-visible regression in update 10. The fix is safe and has very low regression potential.
