v4: a case of amscd overlapping in SVG

[pkra]

The following example:

\begin{equation*} \begin{CD} P \times ^H F @= (H \times Y \times F)/H @>{\simeq }>{(h,y,z)\mapsto (y,h^{-1}z)}> Y \times F\\@VV{\widetilde{\sigma }}V @VV{\operatorname {pr}_Y}V @VV{\operatorname {pr}_Y}V\\Y @= Y @= Y \end{CD} \end{equation*}

On mathjax.org#demo, this renders with SVG as follows:

CSS looks like this:

which is close enough to TeX output:

Thanks. I'm able to reproduce, and will look into it. I'll let you know what I find.

A reduced test case is

\begin{CD} 
A @= B
\end{CD}

It turns out that the minsize setting on the stretched equal sign isn't properly setting the bounding box to that size. I'm still looking for where that is going wrong.

Thanks, Davide.

I have made a PR that resolves the issue. Do you need a patch to use before the next release?

Thanks for the offer but I think we can wait until a release (or it lands in the develop branch).
