These were added so chromevox properly updates the highlight
location when transform animations complete. Previously, the view
location was updated only when view bounds changed. This has since
been addressed in the views code, so app list specific workarounds are
no longer needed.

TEST=Enable chromevox, show the partial launcher with the highlight on
the search box. Expand the app list to fullscreen. Verify that the
highlight stays with the search box.
