Details

This warning is printed for every crashtest AFAICT. We should fix the underlying issue. https://tbpl.mozilla.org/php/getParsedLog.php?id=30865332&tree=Mozilla-Inbound
The reftest harness looks for DOMAttrModified events to find when class="reftest-wait" is removed for reftests that need to do work onload: http://hg.mozilla.org/mozilla-central/annotate/3c4fc4279e6a/layout/tools/reftest/reftest-content.js#l474 I don't think it's particularly complicated, probably an easy fix.
Use a MutationObserver? (new MutationObserver(function(r, m) { m.disconnect(); AttrModifiedListener(); })).observe(contentRootElement, { attributes: true })
