(This is mentioned in the status report
http://www.mozilla.org/projects/mathml/update.html but deserves mention in
Bugzilla.)
Mozilla doesn't yet support <maligngroup> in MathML. This is needed to
correctly lay out multiline displayed equations as in the follow example (or
see example in section 3.5.5.8 in the MathML spec).

This is a much-needed feature for formatting multiline equations. It's shocking that no activity has occurred in this bug during the last 10 years!

<maligngroup> is not part of MathML Core and it's even considered for deprecation in MathML 4: https://github.com/w3c/mathml/issues/181
So I guess this should be WONTFIX.
