manu overlap depending on body margin

On this page using MathJax 3

https://pretextbook.org/examples/sample-article/crc/section-fundamental-theorem.html

the MathJax sub-menus overlap, depending on the body margin.

If the page is narrow, everything is fine.

But when the page is wide, so that the content is left-right centered
because of

body.pretext {
margin: 0 auto 0 auto;
}

then the sub-menus overlap.

Pictures available here

I see this in Firefox, Chrome, and Safari.

In the inspector I see that the structure of the menus is
sibling divs:

div.CtxtMenu_ContextMenu.CtxtMenu_Menu
div.CtxtMenu_ContextMenu.CtxtMenu_Menu

and each of those has a left and top style inline. When the page
is narrow, the two lefts differ by a small amount, which is what causes
the overlap.

I could not figure out how to change that inline style, nor why the
body margin made a difference.

I am pretty sure it is the body margin because disabling the margin
CSS shown above eliminates the problem.

Thank you for any help,

David

David W. Farmer writes in part, quoting someone's output:

body.pretext {
margin: 0 auto 0 auto;
}

... as if there could be more than <body> ??

Dear Bill,

Not sure if you were attempting humor.

It does make some sense because a lot of foreign css can be
at work in a PreTeXt document.

So we try to use the .pretext everywhere, to over-ride non-PreTeXt
selectors (which in many cases style on the tag and not a css class).

Regards,

David

Since this is approaching nearly a year old, I suppose I can interpret this as "won't fix" on the MathJax end.

Is there anything we could do to adjust the PreTeXt CSS to keep the page centred, but also keep the MathJax menus working?
