I've observed with with Atlassian where I wanted to report a Jira bug, but found that it had already been opened some years before, more than a hundred people had subscribed, bug was still closed as "no activity, must not be relevant". I just found the exact same bug reported for Jira Cloud (I had observed it in the on-prem version): https://jira.atlassian.com/browse/JSWCLOUD-8865 and it was closed there for the very same reason.
I didn't leave a comment because the original report described the issue perfectly, and adding a "me too" comment is just noise in the bug tracker. Guess I'll be noise in future :-(
