Mathematik in Umfragen rendern

[merry]

Similar issue to this post.

Math does not render inside a poll.

It renders in the compose post screen but not in the poll itself:

Inspect element reveals <span class="math"> … </span>. Can someone point me in the right direction how to fix this please ? (Assuming the solution is similar to the above-linked post)

I couldn’t make this work either. Seems like a bug to me.

When adding math formulas to a poll they are rendered correctly in the preview

But not in the post itself:

When inspecting the source code, I saw formulas are rendered in <span class="math-container inline-math mathjax-math"> ... </span> but in the polls, formulas are rendered in <span class="math"> ... </span>. If I test it in safe mode (with plugins disabled) all formulas are rendered in <span class="math"> ... </span>. Which makes me think the math plugin doesn’t work with the poll plugin.

As an alternative, you could put your formulas outside the poll, and then reference them in the poll like so:

Ich weiß nicht, ob mathematische Auszeichnungen in Umfragen unterstützt werden, @sam.

[sam (Sam Saffron)]

Ja, ich glaube nicht, dass wir dafür Unterstützung eingebaut haben. Ich schätze, ein PR ist willkommen, um das zum Laufen zu bringen.

MathJax not working in poll options

I’m afraid you won’t learn much from the change, it’s a little bit of a dark magic change. Poll is an old plugin and it’s probably doing something incorrect which forces me to do this here. I saw the issue but honestly didn’t dig the root cause as this interaction discourse-math/poll is quite a niche subject in our codebase and couldn’t justify spending days on it.
