Steps to replicate the issue (include links if applicable):
- Go to https://en.wikipedia.org/wiki/Wikipedia:Featured_lists
- Go to Appearance
- Enable dark mode
- Click on Report an issue with dark mode
- This should redirect you to this page
- In the text editor field, switch to visual editing
What happens?:
Returning to source editing (in the preview) or simply submitting the report, should show that everything (including the title of your report), was removed except the non-comment text that was in the text editing field before submission (example that showed this issue to me)
What should have happened instead?:
Only new text should be added to the page
