Research Popover API usage (for non-modal?) dialogs.

Definitely great for the off-canvas "rewrite" in 🐛 Module breaks Layout Builder or any module using the core "drupal.dialog.off_canvas" library Active !

Hey gang, I finally came around to finding this issue. I've done some preliminary work here. It might be good to discuss the approach we want to take. Drupal provides a whole separate render path for dialogs, along with a custom Renderer and drupal ajax support.

What are the goals here? Is it:

* Feature parity with Drupal core?
* A means to inject a different implementation of the dialog that completely replaces the off-canvas dialog with a new implementation?

Let's discuss

@cosmicdreams thanks for your comment! Re #4 I think we need both:

• Compatibility with existing Drupal.dialog() calls that exist in core, contrib and custom
• "A plan for a brighter future" ;)

The point is, that I think we need someone from the Drupal Core team to discuss this with us and make lasting key decisionsfor the API.

Does someone here know someone who knows someone who knows the right people to get into this topic (aka 📌 Add a native dialog element to deprecate the jQuery UI dialog Needs work )?
(We should move this discussion into a separate meta-issue or the core issue or something like that to not clutter the technical discussion here)?
