Issues not removed from a list when time range is exceeded in real time issues / feed

### Environment

Self hosted

### Steps to Reproduce

1) I select projects, env and time range (30min) + only unresolved error or outage and turn on real-time updates (the play button)
2) New issues pop up in the list, that is ok
3) Issues grow > 30min old
4) Issues should therefore disappear, because they do not match the time range anymore
5) Issues persist on the page

### Expected Result

Issue is not shown on the page because it has last seen date is > 30min ago (e.g. 2 hours)
AKA - no bugs anymore 🥳

### Actual Result

Issue is still shown on the page, even if last seen is > 30min ago (e.g. 2 hours)

When doing a full page reload, issue does disappear.

This makes it look like there has been a problem in the last 30 minutes, which it hasn't.
