BUG: Cropping User Interface

HARDWARE:
macOS Monterey, Version 12.2.1
MacBook Pro (16-inch, 2021), Chip Apple M1 Pro

SCREENFLOW:
ScreenFlow Version 10.0.5 (31892)

SUMMARY:
When invoking the capping tool, I can drag the right, top and left edges easily, but the bottom edge is not selectable.

STEPS TO REPRODUCE:

1. Click the crop button
2. Hold Shift and drag the top, left and right edges as descried
3. Try to grab the bottom edge - the cursor turns to a drag cursor, but it cannot be dragged

EXPECTED RESULT:
I should be grab the bottom edge just as easily and drag it.

ACTUAL RESULT:
The bottom cropping edge is obstructed by Screenflow's timeline UI. I have to zoom out to less than 70% to grab the bottom edge.

SOLUTION:
When entering crop mode, auto-scale the video down to a size that fits within the viewable region. It appears the bottom edge of the video needs a few pixels of space to allow me to see/drag the bottom cropping edge.
