Summary	0010420: Crash when expanding the boundary of a split region in the pianoroll
Description	After splitting a long MIDI region, deleting the left-hand part, and moving the remaining region to the beginning of the timeline, an empty area is still visible on the left side when the region is opened in the pianoroll. Attempting to expand the region boundary into this empty area causes Ardour to crash with the following assertion: ardour-9.7.90: ../libs/ardour/location.cc:344: int ARDOUR::Location::set_start(const Temporal::timepos_t&, bool): Assertion `_start.is_positive() \|\| _start.is_zero()' failed. Aborted I believe it's related to 0010136 as the root issue seems to be the same.
Steps To Reproduce	1. Create a new session. 2. Create a fairly long MIDI region (about one minute long). 3. Zoom out so that the entire region is visible. 4. Draw a few notes in the last couple of bars. 5. While still in the editor, split the region just before the first notes, delete the empty left-hand region, and move the remaining region to the beginning of the timeline. 6. Open the region in the pianoroll. Notice the long blank area on the timeline before the region begins. 7. Still in the pianoroll, drag the left region boundary one bar or so to the left, overlapping the blank area. 8. Ardour crashes.
Additional Information	A full gdb backtrace is attached. Link to the video showing the issue: https://oc.lh2.pl/s/BPgkekmccSdxsRm
