Discuss bugs in itex2MML.

(Repost from the other discussion as this looks buglike to me.) Okay, let’s try this here. Compare and contrast: How it ought to look: $$\underset{n\to 0}{\mathrm{lim}}\frac{1}{n}=0$$
With a $${{\displaystyle \mathrm{lim}}}_{n\to 0}\frac{1}{n}=0$$
Now with a bit of grouping to help. $$\underset{n\to 0}{\mathrm{lim}}\frac{1}{n}=0$$
Somehow, the

It’s a matter of the precedence rules that you expect not being respected by itex2MML
is set with an
the precedence of the ”
which is set with an
gives you what you were expecting. I think this is confusing. Probably, you were expecting Update:Let’s see: $\underset{n\to 0}{\mathrm{lim}}\frac{1}{n}=0$ $${\mathrm{lim}}_{n\to 0}\frac{1}{n}=0$$
Yup. itex2MML 1.4.8 works as you’d expect.

This looks like a bug in how Firefox renders MathML, but I thought I’d check with you first. How do $\hat{\otimes}$ and $\hat{\otimes}$ look to you? To me, the first has the hat offset to the right. I presume that it shouldn’t be so.

Correct. The accents work correctly when accenting an Thus:
You should file a bug report.

(My word, but that’s a complicated form. “What did you do?” I looked at a MathML web page. “What happened?” It didn’t look right. “What should have happened?” It should have looked right.)

‘Cept it’s not a Firefox bug; it’s a Gecko Core (MathML Component) bug. As filed, no one relevant will see it. If you, as the Reporter of the bug, can reclassify it, maybe it will have a fighting chance of getting some attention.

Identifiers lumped together in MathML output Example: Output should be more or less ${X}_{a}b$ Two things wrong with this: first the “b” would never be subscripted in LaTex, and second, two variables should not be lumped in the same

Good enough then and thank you. I thought
