Ah, right. There is an interactive function bound to a key which runs
track-mouse ... etc.

Okay, that makes sense then, yes - it seems reasonable.
Arguments could be made against this:
- This could break existing packages that use long running commands
and expect the idle timer to run.
- Any developer running into this situation in the future (idle timers
and track-mouse that is) - might reasonably expect idle timers to
activate when the user isn't moving the mouse.
However if the change in behavior is acceptable by emacs developers,
I'm not pushing against it - just noting some possible down-sides.
