Angle brackets not escaped in Markdown output

[telotortium]

For example, the text <h1>1. Hello world</h1> is copied to the Markdown output <h1>1. Hello world</h1>, rather than the proper escaped version \<h1\>1. Hello world\</h1\>. I've filed a bug to turndown, since it looks like they're responsible for the escaping: mixmark-io/turndown#395

This is because if you don't have everything selected (to the closest parent), everything would be considered plain text.

<h1>1. Hello world</h1> out of context is considered plain text, not piece of code. This isn't a bug in turndown, but is a nice feature for this to see what the closest parent is and use that instead from the extensions end.

I haven't touched the codebase in over a year, and don't remember most of the internals, so I might be wrong at multiple levels. I'll have a look when possible, or feel free to yourself.
