Fix markdown rendering issues, with font size and images.

[dessalines]

Realized we don't have an issue for this yet, even though ppl are contributing PRs like #432 .

The main alternative to jeziellago:compose-markdown, is likely https://github.com/halilozercan/compose-richtext . But last time I tried this, it didn't support images well.

It might be viable to upstream some image support/image fixes.

Don't know if this should be in this issue or a separate one, but in general the markdown rendering in Jerboa is not up to par: https://aussie.zone/post/3604

The web UI and apparently also mlem on iOS seem to support all this.

At least some of these markdown issues are new. I swear I successfully used subscript a week or so ago.

We changed the markdown renderer in 0.0.33 to fix a number of other issues. Seems like the new renderer supports fewer features out of the box.

Another thing that's been bugging me to hell (not new though AFAIK) is that most numbers (>1 digit) are turned into clickable tel: links (phone numbers).

I don't know if this is fixed with the new renderer, but besides spoilers, strike-through text does not work for me. In addition to that, there doesn't seem to be any rendering of Markdown in the overview cards, which is especially bad for spoilers. If you want me to create a separate issue for this, I'm happy to do so.

This is my post on Lemmy regarding this issue:

[bappitybup]

is it intentional that markdown doesn't apply if the start and end of it are on new lines?

[twizmwazin]

I'm going to mark this as complete because the original issue has been fixed. If there's a specific markdown feature that we should support that isn't supported, please open a new issue specific to that missing feature.
