Fix bubble manage menu position after rotation

The orientationChangedListener is trying to reopen the menu after
rotation but there are 2 issues that prevent the manage menu from
reopening correctly:
1. onDisplaySizeChanged may be called after we try to show the menu,
which resets it
2. the manage menu position depends on the position of the manage
button, which needs a layout pass to recalculate after rotation

This change updates onDisplaySizeChanged to re-show the menu if needed
and posts it to the looper.

       - Observe that the menu is positioned correctly after rotation
