----------------------------+-----------------------------
 The TinyMCE editor fails to initialise properly when using a combination
 of Gutenberg, and SCF/ACF WYSIWYG fields.  On page load the Visual Tab is
 empty, if you switch back from Text to Visual the JS console produces the
 following error:

 wp-tinymce.js?ver=49110-20201110:3 Uncaught TypeError: Cannot read
 properties of null (reading 'setBaseAndExtent')

 Rolling back to 6.6.2 resolves the issue, as does using ClassicEditor
 plugin.
