Reland "Prevent dismissing starting window when reopening app"

If we are changing the visibility while the app is shortly before
drawing it's first frame, we cleared out the draw state, leading
to a hang. We also had this issue with starting windows, but that
was a fix only for starting windows, but cascaded the underlying
issue.

Now, we only clear out the draw state if is has fully drawn - this
covers the Chrome case but doesn't clear out draw state if it's
just about to show.

Furthermore, we also add the window to mResizingWindows such that
the client is expected to call back to us with reportDrawn, in all
the edge cases.
