Different math symbol display (LaTeX) depending on color settings
Goog morning,
I would like to point out the following issue. I have with Firefox 109.0.1 on Linux Kubuntu 22.04 a display problem on the page
https://www.lmfdb.org/NumberField/2.0.4.1
Right at the bottom is some "LaTeX code" text which is displayed in two different ways:
1) If I leave the default settings for the colors it is "p ≢3 (mod 4)"
2) If, as in my case, I set the background color as gray (to have less brightness "shot" on the eyes) and I tell Firefox to use the personal settings "always" instead it is "p ≡ 3 (mod 4) "
Note that, selecting the LaTeX text and copying it somewhere else, I get $p\not\equiv 3\pmod 4$, so the "negation bar" is actually present: I don't understand the reason of this behavior and how to manage it.
Thank you in advance, best regards.

It look like the katex-html code doesn't have the code to show the '/' on top of the equal '≡' (<span class="mrel">≡</span>) like is done with the katex-mathml code (<mo>≢</mo>). So if disabling the website code makes Firefox switch to the katex-html code then that can cause the '/' to get lost. I don't know whether the website generates both versions of the code or that otherwise something goes wrong here.
Thank you very much. I reported your answer to the site managers, now I'll wait for an answer of theirs. There is therefore nothing I can do with (or set in) my browser in order to solve the problem, isn't it?
