Request: I believe there is a way for devs to purge/reset notifications for a user when this (very rarely) happens. Please do so for me! https://wikitech.wikimedia.org/wiki/User:Quiddity (User ID: 1884)

If you know of it, could you point me to a task or some documentation for how to do this? I am not familiar with how to do that.

I don't know. The closest things I'm familiar with (and I'm not sure if they're relevant) are:

1. the line of JavaScript that was suggested years ago, for running in browser-console. I tried that, and it doesn't work. Possibly it needs tweaking for the modern codebase?
   • new mw.Api().postWithToken('csrf', {action:'echomarkread', all:1});
2. whatever the devs did in T141816: Cannot see or clear unread notifications at Beta Cluster. IIUC that was related to a deleted page, but it was a Structured Discussion page (which don't exist on Wikitech) if that matters.

@Quiddity - Is this still an issue? Are there other reports of this happening?
