App displays a background for custom emotes when it should be transparent

[Koakuma-spec]

Steps to reproduce

1. Type in custom emotes using /html. Here is one example: /html <img src="mxc://midov.pl/eef5810eddf6b07d412d44ab9771e46ce774f188" width="32">
2. Send it
3. Hover over it - whether you're using a light or a dark theme, it is there. It is ESPECIALLY visible when the user is using a custom theme.

Additional note: I think this "bug fix" may have been responsible for it.
Additional note 2: Because to temporarily fix this, I have to go into DevTools and manually uncheck the background color box under .markdown-body img. I also did not see this background in previous versions of element.

Additional note: I think this "matrix-org/matrix-react-sdk#12628" may have been responsible for it.

Doesn't look like it, your screenshot shows that it comes from https://github.com/sindresorhus/github-markdown-css
