What?
Extracted from #60735.
Fixes #13318.
This PR preserves HTML comments in rich text. Currently they are stripped out when HTML is parsed by rich text.
Why?
We should leave the content intact and interfere as little as possible. While useful on its own (and fixing a bug), this is also a preparatory PR for Bits, as it will make use of comments to anchor dynamic content inline. In the editor, the comment will then be replaced through an API by either a placeholder or the data.
How?
Rich text uses the browser's HTML parser, so it's quite easy to store this internally.
Testing Instructions
Insert a comment in a paragraph (through the code/HTML editor) and switch back to visual. There should be a placeholder. Edit the paragraph, and the placeholder/comment should remain.
