Possible solution. I'm not sure, though, whether that might have unwanted side effects. @manu37, could you please have a look.

Is this the 1st occurrance we use tinymce5_replace()? This is really a bug. As I see it, on tinymce5_replace() the hole config establish is missing and the solution above solves that. I don't see any problems with this fix.

There are probably only few plugins which call editor_replace(). I only do that in Coco_XH, and that has the same issue (no editor without the fix).
