Issue Description

The target-size #incomplete7 and #incomplete8 rule integration tests fail on Firefox 131 (nightly as of writing) due to https://bugzilla.mozilla.org/show_bug.cgi?id=1912115 - Firefox incorrectly calculates the computed dimensions of a certain test <img> element without considering the explicit width/height on the element like it ought to (and like chrome and older firefox versions do).

We'll be adding a workaround to the tests to suppress the failure. If firefox fixes the bug in a timely manner, this issue will track removing the workaround; if they don't fix the bug, this issue will track considering a workaround in axe-core itself (eg, waiting an event loop tick at the start of axe.run)
