I am trying to understand how "UV Unwrap" node works and created a really simple setup to test it. I ended up with an unexpected result (see screenshot)

To my understanding, this setup should mark all edges as seams. Unwrapping from there should result in square shaped UV maps. According to what I am seeing, results are not squares and shapes are rotated.

I expect to see square regions of texture on every face. Not stretched or rotated.
