We should allow the <figure> and <figcaption> HTML tags. This will be especially useful for news posts that present charts.
<figure> should be able to contain any HTML we allow, including tags for embedded audio and video.
Closing </figure> tags are required and should be inserted... however we handle closing tags for things like <blockquote>.
It does not need to be automatically wrapped inside a <p> tag – it can stand on its own like a <blockquote> – although it’s fine if a user wants to include it inside one.
You should be able to use the class, dir, or title attributes on a <figcaption> tag.
<figcaption> should be stripped unless it appears inside a <figure> tag, but you can have a <figure> tag without <figcaption>
Closing </figcaption> tags are required and should be inserted before the closing </figure> tag if left out.
