LGTM, do you think it breaks anything else?

I don't, of course, but that's no guarantee. :-/

On the bright side, the code only gets executed when you switch tabs.
If you can think of anything I should test there other than that the
selection gets restored and PRIMARY is untouched, let me know.
(Didn't mention it in the description, but I also checked that the
cursor position still gets restored even if there isn't any
selection.)
