Interesting. Looks like PreferredSizeChanged() invalidates the layout, however,
the relayout never happens? Should we fix that instead?

Discussed this offline. sadrul@ thought we could have 'ScheduleLayout()',
similar to SchedulePaint(). We already have InvalidateLayout() and perhaps that
could ensure that Layout() happens before the next paint.

Still in this case it is the Layout that triggers paint and there is nothing
else in this scenario like resizing to trigger layout or paint. This makes it
tricky.
