Re: MathML Core Meeting on Monday April 24, 2023

Thanks for pointing that out. I believe you are correct that it is a font
issue. I remember seeing that during the beta. I think I brought this up
and Fred said it was bad info in the OpenType math table for some fonts,
but it is possible I'm misremembering.

I was going to mention that the referenced bug report is really about the
width calculation for vertically stretched chars (height for horizontal
stretching), but that's not the rendering issue that was on stack exchange
so I didn't want to muddy the waters.

@Dave Barton: if you use a web font, does this significantly lessen the
severity of the bug in your eyes? Or are you more concerned with the chars
crashing into each other. I tried a few cases and couldn't see that
problem, but I didn't try very hard.
