As meta box is supported, users might create an extra TinyMCE editor in a meta box, which has the fullscreen (DFW - distraction free writing) mode. When clicking on the fullscreen button of the TinyMCE, the UI of the Gutenberg overlaps the UI of the TinyMCE editor, which makes the TinyMCE editor useless.
