fix(wm): ensure focus restore on float + max hwnds

This commit ensures that when switching to a workspace which contains a
floating window or a maximized window, either the maximized window or
the first floating window index will be focused.

This is to prevent windows which have been hidden on the previous
workspace from retaining keyboard focus.
