Add images (nested widgets) support in tables.

[jodator]

Follow-up for the #3199 - currently there are some issues with widget in widget (images in tables):

• click select does not work
• ballon toolbar sometimes does not work
• pasted image behaves differently then converted from data - you can edit caption only for pasted
• fake selection sometimes is broken

I guess that images are now allowed (by the schema) in tables. Am I right? So the iteration 20 won't be complete unless we close this ticket or disallow images in tables?

I'm asking because we need to do either A or B.

You're guess is incorrect ;) I've disabled it in the ckeditor/ckeditor5-table#97 PR:
https://github.com/ckeditor/ckeditor5-table/blob/bd5b81d0062cc984d08f6ea456108ede632b7b89/src/tableediting.js#L84-L89

I've disable it after issues with widget in widget (image in table): #3219, ckeditor/ckeditor5-table#99.

OK, cool. So we can postpone this.
