Summary0010345: Piano Roll Window - Opens in large vertical zoom state
DescriptionVersion: 9.4.5 nightly build

I mentioned a few of these in the past, but there still seem to be zoom issues with MIDI track piano rolls and Piano Roll windows.

Piano Roll Window
Opens with a larger vertical zoom state then is actually supported
Steps To Reproduce-Open new session
-Insert a MIDI Track - General MIDI Synth
-Draw a MIDI region in Editor timeline
-Draw some MIDI notes in that new region, in the beginning of the region and stack some notes (as if they were chords).
-Double click on this region to open in Piano Roll window
-You will notice that it opens very zoomed in
-Adjust the vertical scroll bar edge to zoom out
-Then try zooming back into this previous very zoomed in state, you cannot, it stops at a certain point.

Also
-If you close this Piano Roll window
-Then open it again
-You will notice that it opens very zoomed in again
-It does not remember the previous zoom state adjusted to
(MIDI Track Piano Roll does remember state, when you adjust the track height to show/hide the piano roll)
Additional InformationNot sure if this is related to the issue I mention here?

@jean-emmanuel
I imagine there is some overlap between all the different piano rolls available.
It appears that maybe the zoom fixes you made elsewhere may have fixed this issue as well because it does not appear that this issue occurs any longer.
Thank again
