Attachment: Bug 1685895: Use a more-permissive "asserts" annotation for reftest abspos-breaking-001.xhtml. (no review, just adjusting test metadata)

This test recently increased its maximum intermittent assertion count, probably
due to an extra reflow that we sometimes incur due to a font-fallback task
having coincidentally just completed, as described in
https://groups.google.com/g/mozilla.dev.platform/c/VBh6oLm4EbQ/m/dbaJcAe6BgAJ
