Any idea what started this?

Flags: needinfo?(dholbert)

The issue here is: assertion count 6 is more than expected 4 assertions. All six of the assertions are the same ("invalid shrink-to-fit ratio").

I would bet this is due to https://groups.google.com/g/mozilla.dev.platform/c/VBh6oLm4EbQ/m/dbaJcAe6BgAJ causing us to get an extra reflow during this test, which then causes additional instances of this assertion (which spams twice per reflow, or something). i.e. this would've started as a result of bug 1676966, possibly combined with a later reftest-rebucketing.

We should just broaden the allowable assertion range here; asserts(4-6) instead of asserts(4). I can do that.

This test spams the same assertion either 4 or 6 times, with this variation
probably being due to an extra reflow which 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

Previously the test was annotated as asserting exactly 4 times, but now we
need to allow for it to sometimes assert 6 times instead.

Pushed by dholbert@mozilla.com: https://hg.mozilla.org/integration/autoland/rev/3d623148f28c Use a more-permissive "asserts" annotation for reftest abspos-breaking-005.html. (no review, just adjusting test metadata)
