Thanks for testing this.

Yesterday I pushed this fix (or rather a variant of it) to the "emacs-25"
branch.

When it comes to feature request #18283 -- this sounds like good idea. But
before I add the applescript lines, I would like to read up on the issue a
bit.

I have found the bug database really hard to navigate -- do you know of any
other OS X-related bugs that are still open, I might as well look into
those while I'm at it.
