Hashtag + text without space (ex: #foo) inside code-block is auto-deleted

Another title for this issue could be: Disable markdown shortcuts when inside code blocks, quotes, and other block-level elements

• Go inside a code block
• Try typing a comment like #comment
• It will be removed as you type

I think course of events is:

• Typing #foo triggers the markdown shortcut for headings
• It realizes you are inside a codeblock and bails out (normalization? ¯_(ツ)_/¯ )

So need to somehow tell the markdown shortcut handler that within the context of a code block it should stfu. It still works for bold I bet, but that shouldn't either.
