When hovering over the +1 reaction count, the users popover stays on the loading spinner.
Network request:
GET /discourse-reactions/posts/37529/reactions-users.json?reaction_value=+1
The server receives this as reaction_value=" 1", so the endpoint returns:
[]
Manual request with URL-encoded plus works:
GET /discourse-reactions/posts/37529/reactions-users.json?reaction_value=%2B1
This returns the expected users.
After clicking the reaction count once, the names are shown correctly and hover keeps working until the next full page reload.
The reactions plugin is the bundled core plugin, not installed via app.yml.
