Probably best to have a new return value here, even if touch-action-delay was
only enabled in tests.

Ok, done.  scroll-blocks-on is really just a rename of touch-action-delay (in
addition to becoming more general), but doesn't hurt.  I expect the name may
change again before shipping.  In general we don't need to retain old values
when we just rename, right?
