@Override
void onTransitionStart() {
super.onTransitionStart();
if (!mHeadersEnabled) {
// When enabling headers fragment, the RowHeaderView gets a focus but
// isShown() is still false because its parent is INVSIBILE, accessibility
// event is not sent.
// Workaround is: prevent focus to a child view during transition and put
// focus on it after transition is done.
