​I'm in the middle of a long list of Emacs bugs I am trying to fix, and
this one came up by chance at the same time, because I was suffering from
the bug.

I'd rather have a simple fix that can also go on the emacs-25 branch, and I
don't really have more time to work on a proper fix, sorry.

On the other hand, I think it would be sad to have to wait (perhaps
forever!) for a "good" fix, when an acceptable fix is available. In
particular, no reasonable application is going to expect a request for the
selection to trigger a keyboard input event. So indeed future applications
may need the "good" fix, but no (reasonable) application will be adversely
affected by this fix.
