Steps to replicate the issue (include links if applicable):
- Visit a mainspace article
- Be a patroller
- In Page Curation toolbar, open maintenance tag menu
- tick a tag in the "All" menu
- tick the same tag in a submenu
What happens?:
- writes two tags
What should have happened instead?:
- should only write one tag
- or should warn the user and prevent submission. not sure which yet. up to whoever writes the patch. the former would probably be easier to code
Software version (skip for WMF-hosted wikis like Wikipedia):
