(WebKit::ServicesOverlayController::remainingTimeUntilHighlightShouldBeShown):
(WebKit::ServicesOverlayController::mouseEvent):
If the mouse is pressed or it's been less than 200ms since the mouse went up,
don't allow the highlight to change. We apply the mouse-is-pressed rule to telephone
number highlights as well, unlike the rest of the hysteresis logic.
