But as you well said, respecting images, tables and the like is one thing. The other is keeping fonts.
Anyhow... so many options that a single feature doesn't fit all. The problem with Windows is the lack of a uniform solution to paste without formatting (my complaint) as opposed to macOS.
Oh, to clarify: I meant: "if you're copying text along with images, you probably want to keep the text formatting [fonts etc.] too, whereas if you're only copying text, you probably don't want the formatting either." It's not a perfect heuristic by any means, but I think it'd be better than the current situation.
You have some formatted text (maybe some bold or italic in a line) on a webpage, you want to copy it into an email (lets set aside the argument that email should be text only).
