Description

  • I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
  • I have read the documentation and cannot find an answer.

Describe the bug
Implicit self-closing HTML tags like <img> and <br> fail to load in the MDX editor as they 'have an unmatched closing tag'.

Reproduction
Repro sandbox

To Reproduce
Steps to reproduce the behavior:

  1. First editor fails to load

Expected behavior

renders as a linebreak as supported in most flavours of markdown

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

  • OS: any

Additional context
HTML tags appear to be parsed with the JSX parser, which is expecting a self-closing tag marker or an end tag (to be valid JSX syntax)

renders as a line break.
