When a formatted hyper link of an oEmbed provider is pasted, ask the user whether to paste or embed

Is your feature request related to a problem? Please describe.
A recent version of Microsoft Edge has the built-in functionality that automatically creates a hyper link by copying a URL in the address bar (for details). The problem is for embeddable URLs. If the user unknowingly pastes it in the editor, a plain hyper link appears instead of an embedded iframe. The confusing part of this behavior is that if the copied URL is pasted in notepad, a plain URL is pasted instead of a hyper link normally. In fact, I mistakenly created an issue by thinking this is a bug.

This Microsoft Edge behavior affects the user experience regarding automatic embedding functionality that WordPress provides. End users with little experience with Microsoft Edge might think it is a fault of WordPress or never notice WordPress has such a feature that enables to embed contents by just pasting a single URL.

Describe the solution you'd like

1. Monitor paste events.
2. Do nothing if the pasted text includes multiple URLs.
3. When a hyper link with a single URL is pasted and it is one of the oEmbed providers, do either of:
   a. only allow the URL to be pasted so that the automatic embedding process starts.
   b. ask the user to paste the hyperlink or the URL

Thank you for the ticket! Is this related to #21789? Potentially a duplicate?

Looks like it.

Mind if I close that one in favor of the other? I'll be sure to link to yours from there so the feedback doesn't get lost.

No, I don't mind.
