Summary0008781: insert time erratic behaviour
DescriptionTime inserted at random places. See attached screenshots.
Steps To ReproduceOpen session. Insert time. Tick "move markers" and "apply to all playlists", region behavior doesn't seem to matter. If all goes well, undo / CTRL-Z and repeat. Move between regions and alternate between inseeting time in the middle of a region or at region border. Sometimes time is succesfully inserted twice before failing.

When failing, time is inserted at some seemingly random interval to the left of the edit point. If multiple tracks are chosen, each track may behave differently.

While testing several sessions, Ardour will eventually crash on opening a session.

If edit point is at the region boundary (end), time is inserted at the start of the region instead of at edit point.

If edit point is at the region boundary (start), outside of regions or between region boundaries, insert time behaves as expected.
