Issue with Character Data (CDATA XML tag) #1858

Open ghost opened 3 years ago

ghost commented 3 years ago

Describe the bug

Adding a Character Data (CDATA) tag <![CDATA[something]]> in the WYSIWYG or markdown view will break the editor. The HTML generated will be incomplete and a JS error is triggered when going from markdown to WYSIWYG.

Uncaught TypeError: Cannot read properties of null (reading '1')
