I can't reproduce it (using master under macOS).  Does the problem
still occur for you?

Thanks for looking into this!  When I visit the same web page in EWW,
Emacs version 25.2.1 (I moved back to using stable releases), I do not
see a formula at all.  Since this issue is better explained in a
picture, I have uploaded a screenshot of this:

Thanks for the screenshot.  It looks like the problematic HTML is this
(the source code for the TeX formula):

I doubt we support the code between the <math> tags, so I think what
/should/ show up is the "fallback" SVG image that Wikipedia provides:

<img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/8411fe69f79f2971b7c7a453b0b547bb37e9f6df" .../>

Please experiment with SVG files (such as the one above) to check if
they all have this rendering issue in Emacs.

Thanks in advance.

ImageMagick and Emacs refuses to display that image:

arsi@corrigan:~$ display /tmp/a.svg
display-im6.q16: width or height exceeds limit `/tmp/magick-27365hcL0Svs4ikfZ' @ error/cache.c/OpenPixelCache/3802.

It's a weird image and starts with

<svg xmlns:xlink="http://www.w3.org/1999/xlink" width="57.793ex" height="6.843ex" style="vertical-align: -3.005ex;" viewBox="0 -1652.5 24883.2 2946.1" role="img" focusable="false" xmlns="http://www.w3.org/2000/svg" aria-labelledby="MathJax-SVG-1-Title">

That's...  some viewbox.

Anyway, this is not an Emacs issue, but an issue with the SVG libraries
Emacs uses, so I'm closing this bug report.
