SSIA. In our mathml.css, for: math { math-shift: normal; math-depth: 0; } are missing. Just raising, so I can fix it. Web-Spec: https://w3c.github.io/mathml-core/#user-agent-stylesheet Thanks!
I don't think WebKit has support for 'math-shift' and 'math-depth' so adding them will not do anything. So will leave this to other time.
