Twenty Nineteen: WordPress embed width does not match between front and back end

As originally reported by @bph on the Twenty Nineteen GitHub repository:

It's possible this applies to more types of embeds as well.

If you look at get_oembed_response_data(), WordPress embeds have a default max width of 600px, which is what you see on the front end.

That max width should be respected, so the width as shown in the editor screenshots are wrong IMO.
