CF8 - 8.0.16 - Textarea + WYSIWYG Editor

Hello Max... On page 4 I have 4 text fields + editor, both required.

1. copy & paste is not recognized as input.

2. If 1 field is not filled in or is filled using copy & paste, both text area fields are always displayed as missing input and in red. This must be related to the WYSIWYG editor.

3. A one-liner without a final enter/return is also not recognized...
