ComboBox: use deferred execution
As a special case, ComboBox defers the execution of the popup until
the popup is either accessed or made visible. This gives a nice boost
in creation time benchmarks (20->25, ~25%). The old optimization of
setting the delegate model only when the popup is visible is no longer
needed.
