This one does the transformation after the path has been set but before the draw. All PDFs I have seen do the transformation first. I could not find which way is correct by looking at the PDF specification.

I can reproduce this using Firefox 70.0.1 (64-bit, Linux). There are no warnings/errors in the console.

Looks like a duplicate of #10908.
