Pasting into the task description doesn't preserve <sub> and <sup> tags

Description

Vikunja's task description editor is an HTML WYSIWYG thing. Is it intentional that it does not preserve <sub> and <sup> tags when pasting?

Even though most of the time I wish we had a simple markdown editor, the HTML thing has one big advantage to how I use Vikunja: sometimes, I copy-paste chunks from webpages that a task needs to reference instead of adding just a link with a fragment both to avoid having to go there again in the future and to get rid of the risk of having a broken link in a few months. When I do that, it basically just works and that's fantastic. Except for the <sub> and <sup> tags.

That can actually really impair legibility in some cases. Is this easy to change? Is there a reason not to change it? Having <sub> and <sup> buttons in the editor would also be nice, but I don't think I would use them often.

I chose the "Bug" type, but feel free to change it to a feature request, if that makes more sense to you.

Yes

No response

No real reason, maybe only due to the fact that you can't set sup/sub text in the editor. Would love a PR to fix this.

And would it be fine to just allow it when pasting, or is it the only way to make the editor support it?

[kolaente]

IIRC the editor only renders what it supports. That means in order for it to allow pasted content like this, it will need to support it in general.

There is a mark which supports this in the core, so integration should be relatively easy:

This issue has been fixed in #3606, please check with the next unstable build (should be ready for deployment in ~30min, also on the demo).
