 * Dear Thomas,
 * thank you so much for supporting the KaTex Plugin. It is a great help in teaching
   math from a distance these days.
 * I came across a small issue whith KaTex rendering big brackets embracing the 
   matrix environment like this:
    [latex] \vec{v}=\left( \begin{matrix}0{,}75 \\-
   2{,}5 \\ {-1}\end{matrix} \right) [/latex]
 * Apparently the upper part of the brackets is being rendered too tall. The issue
   comes up both in inline and display mode: See inline mode right [below the image](https://schulblog.net/fus/licht-und-schatten-mit-ebenen-im-raum/).
 * KaTex: Latest version
    Theme: Koji by Anders Noren, latest version Custom CSS:/*
   won’t have any impact to the rendering issue */ .katex svg { max-width: none;}/*
   required to render vector arrow correctly */ .katex-eq {font-size: 93%;} /* match
   font size with theme */
 * Thank you and take care
 * Jürgen

 * Dear Jürgen,
 * Thank you for your kind words.
 * I’m seeing the same issue. The problem is upstream: it’s also present when inputting
   the expression on [https://katex.org/](https://katex.org/)
 * I found there is already an issue report ([https://github.com/KaTeX/KaTeX/issues/2198](https://github.com/KaTeX/KaTeX/issues/2198)),
   and a potential fix ([https://github.com/KaTeX/KaTeX/pull/2234](https://github.com/KaTeX/KaTeX/pull/2234)).
 * We’ll have to wait for a new KaTeX release, which unfortunately might take a 
   few months still. I’ll mark this issue as resolved as there isn’t much this plugin
   can do about it at this moment, but do keep an eye on new releases.
 * In general a plugin like WP QuickLaTeX would have better rendering as it uses
   actual LaTeX, but it has its own cons (it’s slower and relies on remote servers
   or a local LaTeX install).
 * Take care, and I’m wishing you good luck with the distance education!
 * P.S. `.katex svg { max-width: none;}` should not be necessary, so something in
   the CSS is probably globally styling `svg`.

 * Thanks Thomas for your quick reply. We’ll have to wait for teh KaTex release.
   I really like the KaTex approach and the issue isn’t so bad at all.
 * PS: The CSS is required for the Koji theme only.
 * BTW, may be you can help me with one more problem: I use the custom CSS .katex-
   eq {font-size: 93%;} to match KaTex font size with the themes font. However, 
   when KaTex is embedded in an accordion structure the font-size turns back to 
   normal. Can you tell me how I can set the font size that it is going to be adjusted
   in all structures?

 * Hi Thomas,
 * The issue concerning the large brackets is settled since V2.1. Looks much better
   now.
 * Thank you very much!
