Describe the bug

I have set up a Label management based on the #News tag.
Since I upgraded to 1.28.0, it somehow includes topics tagged with the much broader #Linux & Open Source News tag.

To Reproduce

1. Subscribe to both https://www.canardpc.com/cat%C3%A9gorie/jeu-video/feed and https://linuxiac.com/feed/
2. Go to Subscription management → Label management
3. Add a label named Brèves, with #News tag as a filtered action.
4. Watch My Labels → Brèves being populated by both #News and #Linux & Open Source News tags.

Expected behavior

Labels should be filtered according to the exact tag (i.e. #News) and not add an invisible glob to include the broader #Linux & Open Source News tag.
