Recover focus on size change in ListView

This CL fixes a bug in ListView where if items are not selectable,
not focusable(in terms of ListView flags) but get focus (because
they can), ListView would not recover the focus properly although
it would make the child visible.

The major issue seems like AbsListView marks data set changed when
the list resizes. It seems like a workaround for some other issue
and the code is from 2009 so instead of changing it, I've decided
to implement a workaround to minimize the potential of breaking
something else.
