[tag:bug] [tag:status-review] [GH #183](https://github.com/StackExchange/Stacks-Editor/issues/183)

Standard HTML (when used to add different heading levels in the header of a **table**) does not render properly in the rich text view. Moreover, switching back to Markdown completely destroys the table:

[![enter image description here](https://i.sstatic.net/6FHn0.gif)](https://i.sstatic.net/6FHn0.gif)

It only renders the HTML **after** posting the answer (provided you've not switched back to Markdown before posting).

Test:

| <h2>left</h2> | <h1>right</h1> |
| :------------ | -------------: |

Compare with the old editor (the HTML is properly rendered in the preview):
