not really intentional (just overlooked).  Generally when I'm testing the
variants, that's using tack (which doesn't test the mouse).

For testing the mouse features, I used vttest.  So there's a blind spot,
which would be filled in if there were cooperative terminal developers.
There're not many of those :-)

...will fix (thanks)
