@d2weber@mastodon.green Good to hear this is not an issue in your case.
I'm not at all versed in cpp, but that code to me looks like it would attempt to load the external resource. At some point is must load it to display/render, does it not?
Perhaps CSS uris are loaded slightly differently from HTML uris like with
![]()
.
There are many ways to load things from external resources, but most seem not supported by the rich text - luckily. Web fonts would've been another possible issue for example...
