This is now all fixed see:

> [@CommonMark testing started here!](https://meta.discourse.org/t/commonmark-testing-started-here/65121):
>
> Per our [migration plans](https://meta.discourse.org/t/discourse-commonmark-migration-plans-confetti-ball-balloon), I just enabled [markdown.it](https://github.com/markdown-it/markdown-it) at Meta. It is an excellent [CommonMark](http://commonmark.org/) compliant engine. I expect quite a few edges to be found during this period of testing. Do not open bugs about the new Engine, just reply here. I/we will be updating the top post here with the list of issues and striking out stuff as it is fixed. Current known issues (to be fixed)white_check_mark Onebox vanishes after you start typing and works not-super consistently white_check_mark pending…

Can not repro any of the issues, also we stopped hoisting code blocks so this can not happen anymore.
