Control: call view, THEN focus, to activate.

This has the unpleasant consequence that view calls arrange itself and then
activate should call arrange too after focusing. But factoring everything out of
view just to avoid calling arrange twice is overkilling and, besides, view is
heavily modified by pertag, so we will be entering a patch incompatibility
nightmare sooner than later.
