Onebox for WordPress 4.4 sites

Hmm. Yeah idk why the height is wrong. The image size is actually ok. When I try to embed the post in WordPress it looks fine.

Either way, the blockquoted link above the embed should be hidden, right?

blockquote.wp-embedded-content {
    display: none;
}

Height appears to be 338 for anything (notice the whitespace below this embed):

It resizes inside of WordPress posts though (visit that link and watch the page load). So maybe there’s something going on in Discourse preventing it from resizing correctly?
