1) New "Guitar Tablature" template (so, common type) -> Finish -> Add some notes with different note values (half notes, quarter notes, 8th, etc.), or open this file: test file.mscz
2) Right-click -> Staff Properties -> In "Scale" box, change the default value (100,0%) for eg 250,0%
- Expected result: the stems of the beamed notes and unbeamed notes remains aligned, on the same "basis"
- Current result: the unbeamed notes (quarter notes, half notes) have an unexpected length by extending to the bottom.
(of course, same related result with a scale eg 50,0%)
