Summary0010278: ui hangs when selecting automation points from outside of the automation track
DescriptionWhen selecting an automation track, and the selection starts *outside* of the track rectangle, sometimes the UI hangs for a while.

This also happens with latest Ardour nightly.
Steps To Reproduce* Start a new project
* Add a midi track with any automation (I've tried with bender and controllers).
* Repeatedly write an automation track and select it.
* UI will eventually lag.
Additional InformationI attached gdb and added the following dprintf:

dprintf Editor::point_selection_changed, "Editor::point_selection_changed\n"

When the hang happens, you can see that this callback is called thousands of times.
TagsNo tags attached.
