Steps to replicate the issue (include links if applicable):
- Go to a talk page
- Click the "new section" tab
- Type #Test for the heading
- Fill in some random text for the message
- Save the edit
- Go to the history tab
What happens?:
- Edit summary is →#Test: new section
- Clicking on that does not jump you to the right section. Jumps you to the non-existent "Test" section instead of #Test section.
What should have happened instead?:
- Edit summary should be →##Test: new section
- Clicking on that should jump you to the #Test section.
Software version (skip for WMF-hosted wikis like Wikipedia):
Other information (browser name/version, screenshots, etc.):
- Was not able to reproduce with # in the middle of the section title. So this bug only occurs at the beginning.
- One might think there is no use case for starting a talk page heading with #. But it does happen sometimes in the wild.
