Summary0008807: Ardour 7 crashes when resizing a MIDI region to the left.
DescriptionWith the following output:

ardour-7.0.pre0.1017: ../libs/temporal/ Temporal::superclock_t Temporal::TempoPoint::superclock_at(const Temporal::Beats&) const: Assertion `qn >= _quarters' failed.

Please see the backtrace in attachments.
Steps To Reproduce- Open a new session in Ardour 7
- Add a MIDI track (Reasonable synth)
- Workaround the bug by augmenting the new MIDI track's height
- Switch to Draw Mode and draw a midi region somewhere on the timeline
- Switch to Grab Mode and Resize the MIDI region to the left
Additional Information- Resizing the MIDI region to the Right seems to not trigger the crash
TagsNo tags attached.

Yes, it is a known issues. Please see the "pre-release warning" that shows up every time you start this under heavy development version.

4) Please do NOT file bugs for this alpha-development versions at this point in time.
   There is no bug triaging before the initial development concludes and
   reporting issue for incomplete, ongoing work-in-progress is mostly useless.
