Page layout breaks if editor is maximized and you navigate back in browser

This issue is already reported in both Angular and Vue integrations, probably exists also in React one, which makes fixing it a good candidate for the next common util.

This one is generally related to how maximize works - it is an issue with every SPA application basically. So I think:

1. There should be a way API to "demaximize" editor so custom integrations could use to fix this issue (not sure it will require any changes in CKEditor 4 itself or calling maximize second time does the job).
2. Official integrations should have built-in mechanism using the above so it works out of the box.

Ok, I see maximize command works both ways 👍

We decided to try to cover it in CKEditor 4 itself. In an unlikely event that it will not be possible we could try to cover it here.
