According to MathML Spec, the mtable 'align' attribute can accept a positive or negative integer, indicating the row of the table, to which the alignment should be applied. 1,2,... indicate the first, second, ... row. -1, -2, ... indicate the last, next-to-last, ... row.
Gecko recognizes positive values, but not negative ones.
See the testcase.

Actually, negative values are taken into account but wrongly interpreted: -1 is considered the penultimate row, -2 the antepenultimate row etc

Ah. I was originally going to comment here that dev-doc-needed did not seem to apply to fixing bugs, but I see what was really being asked for was updating developers section of release notes to indicate the bug was fixed. Perhaps we need a different keyword like dev-relnote-needed to make this more clear.
Or perhaps it really should have just had the relnote keyword instead of devdoscs-needed. Devdocs-needed would seem to imply that the developers wiki needs to be updated.
That's exactly what it means. relnotes are user-facing; dev-doc is developer-facing.

Can you please open a new bug?
It would also help to find a regression window: https://mozilla.github.io/mozregression/quickstart.html
