Can you clarify what the actual/expected rendering of reduced.zip is? Here's what I see (Firefox Nightly 133% vs. Chrome 125%). Both show a slightly-odd inverted-curve at the left edge. Is this the problem here, or is there something more severe that the testcase reproduces on some configurations & that I'm not seeing?

For convenience, here's a live bugzilla-hosted version of the previous reduced.zip testcase.

This issue doesn't seem to be a regression, I can reproduce it way back to Fx 39.0a1, on earlier builds I have problems with loading the site.
