I created an object with a stroke, then expanded the stroke so it became a regular shape. After that, I selected it along with another object underneath and tried to use merge function to cut the expanded stroke into the lower object.

Instead of performing the expected merge, VS simply removed the lower object.

I have attempted to perform the same action in default settings and the problem persists.

I have attached a video of the issue

Steps to reproduce

1. Create an object with a stroke.
2. Expand the stroke.
3. Place another object underneath it so the two overlap.
4. Select both objects.
5. Shift M to merge
6. The lower object disappears instead of the overlapping shapes being merged as expected.

Im running O.S. Sequoia 15.6

Thanks for the help!
