Embedding webforms isn't possible if they contain required fields

Problem/Motivation

We can successfully embed webforms in the body field of nodes. But when an embedded webform contains required fields, saving the node is rejected as the webform can not be validated. I wasn't able to find out why the validation is even performed for the embedded webform, but it is certainly the issue.

I haven't marked this as a bug of the embed module, but I would hope that we can at least find a way to resolve this.

A workaround would be to render only the label of the webform when the context is the CKeditor and only render the form itself, when we're in view mode. The same would probably also make sense for embedded views, as rendering their content inside the editor could be a performance hit.

But if there's any other resolution to this, I'd be happy to learn about that, too.
