<!-- Note: In earlier versions of MathML, putting some attributes on the
mstyle element was supposed to produce the same rendering as putting them
on the all descendants (with some exceptions). In MathML Core, relevant
style attributes are implemented as CSS properties and are no longer
specific to the mstyle element. The tests below verify that attributes
on mstyle that are not mapped to CSS have no effect.
