Bug: when you create a frame (with F tool) masks do not work

Not sure if this is how to report bugs. Please forward to the appropriate channels if you know them.

If I create a frame using the ‘F’ tool masking does not work.
Steps:

  1. Create Frame with ‘F’ tool
  2. Create rect inside with ‘R’ tool
  3. Create rect outside with ‘R’ tool
  4. Rearange so that the frame is on top with ‘]’
  5. select both frame and rect and mask with ‘^⌘M’

See frame: not masked.

If I create the shapes first and then ‘⌥⌘G’ to create the frame masking works.

existing issue that was similar:

Clip Content creates a mask around the frame so it can’t be masked directly. Either disable clip content in the frame or wrap it in a group so the group is masked, not the frame directly.
