Details

In bug 1368236 I've added the "hints handled for descendants" optimization, which avoids posting redundant change hints to the change list.

One would thing that such an optimization shouldn't have any effect on the test results, however it makes some new reftests pass, as can be seen in 
https://treeherder.mozilla.org/#/jobs?repo=try&revision=096993697abc0386d7de0a2dc10c4f637122648a.

I haven't investigated them, but I've verified that they're not intermittently passing.
For the record, just in case the try run disappears, they are:

 * layout/reftests/mathml/dtls-2.html
 * layout/reftests/mathml/dtls-3.html
Oh, those are the tests that started failing with Cameron's optimizations, and now pass again... There's something fishy going on there... :(
