Fullscreen issue, mce-fullscreen is removed when inserting image, special char, video, etc that use popup

Hi,

When performing some third party product test, I found fullscreen issue. See Attachment, When fullscreen is enabled and inserting image, video, anchor that use popup, they remove mce-fullscreen class (See Attachment)

It means the css rules to control z-index of tinymce container isn’t used in that point and makes other div elements around it which has bigger z-index value will stack on it.

I tested that on https://www.tinymce.com, seems how the website menu stacks on tinyMCE toolbar, and it makes me can’t click any tinymce’s toolbar button.

I have checked fullscreen plugin code and found that it adds mce-fullscreen class for 3 different divs

var body = document.body, documentElement = document.documentElement, editorContainer;
editorContainer = editor.getContainer();
...
DOM.addClass(body, 'mce-fullscreen');
DOM.addClass(documentElement, 'mce-fullscreen');
DOM.addClass(editorContainer, 'mce-fullscreen');

and they (performing insert with popup) remove 2 of them

DOM.addClass(body, 'mce-fullscreen');
DOM.addClass(documentElement, 'mce-fullscreen');
