Great to see the meta area is no longer hidden, but testing on real life sites runs into countless issues including data loss, locked or messed up screens, links going nowhere, popup windows being cut off, etc etc. (Reported via feedback form).

I get that it's a first cut, but i strongly doubt this is going in the right direction.

Obviously all these issues are caused by using iframes, and it will be a herculean task to fix (or even identify..) these issues one by one.

Maybe the big plugins like ACF Pro, Pods, Polylang, OASIS Workflow that were killed by Gutenberg in our tests will bring their own solutions, but there is a lot of individual work out there that will never be touched. Because nobody will pay.

So looking for an alternative solution without iframes that let plugins work 'as is' would be great.

PS.
Personally i would be fine with Gutenberg replacing only the editor block without replacing the whole editing screen...
