To understand this change see test 1092 on BOS. When you click
Done once and then get the 'click Done again to proceed' warning,
the Done button seems to grows a little dotted line (I think
this indicates it's selected), which causes the match to drop to
94% and fail. To counter that, shrink the match area to the bit
of the button inside the dotted line, which will be the same
whether it's there or not.

See if no_swap stops failing sometimes now, maybe,
at last? Yeesh. Also see if all other tests still run OK.
