CHECK failure with MathML + ::first-letter

Ensure that display: math elements handle ::first-letter the same as
flexbox/grid in order to fix a CHECK failure. display: math elements do
not support linebreaking, so an equivalent testcase for ::first-line
is not possible. The WG is agreeing about whether these pseudo-elements
should indeed be ignored for math layout [1].
