Image Markup Editor Window Cropped while Cropping

With sufficient irony, the Image Markup Editor Window is cut off slightly on the sides while using the crop tool. The window is also non-resizable. For some image dimensions/resolutions, this results in not being able to adjust the crop area.

To reproduce:

  1. In BTT set up gesture to show Clipboard History tool
  2. ⌘+⇧+5 to show the screen capture tool
  3. Select Options
  4. Verify "Save To" location is set to clipboard
  5. Take Screenshot of any area
  6. Activate Clipboard History Tool via BTT gesture
  7. With the recently captured screenshot selected, click "Edit Image (⌘E)"
  8. Select the crop tool
  9. Some of the window, including the Done button, will be cut off
  10. For some image dimensions, the crop handles will also be cut off

It seems like the issue is worse with larger images in landscape orientation, especially those at 4k and 5k resolutions.
