Previously when the window width was reduced, the overlay drawer
was still visible except it was hidden behind the main view.
Taking inspiration from the binding in OverlayDrawer.qml source,
I set up a callback to match it closely. Now, it closes the
drawer when the window is resized.
Note: Both before and after this commit, there is a warning when
one collapses the window width.
