nit: Add a description, i.e.:
Tests that when a child window gains focus the top level window containing it is
resized to fit the remaining workspace area.

Can you make methods in WorkspaceLayoutManagerKeyboardTest for
Focus(TextInputClient or Window) and Blur() (lines 1079-1083) to avoid
duplicating this code in both tests?
