Onebox looks horrible on Discourse Comments (below WP Post)

Hi @simon

Thanks for your reply and your help.

I managed to clean up the onebox styling a bit with your suggested CSS (01.29.2018-14.27.06 - TechSmith Screencast), but there is still some undesired HTML being parsed, like an H3 header. Does the Discourse Wordpress plugin offer any hooks so I can overwrite the HTML output?

Or perhaps this is a great suggestion to improve the Discourse Wordpress plugin?

Looking forward to your reply. Thanks!

    display: none;
