Describe the bug

Since some time last week (at least from June 18 and forward), I see a notification with the message maximum of series (500) reached for a single query "all the time" when I browse our logs. We run on Grafana Cloud.

For example, I see it when I set the time period to the last 6 hours for one of our apps. I don't see it when I set it to the last 3 hours.

My colleague (@jage) suspect it has something to do with the "Patterns" – when the period is set to 3 hours, the number next to "Patterns" is ~430 (it varies).

Is it that the number of patterns exceeds 500 when 6 hours is used as the period?

Is it related to 7f1df4c? (A commit @jage linked my earlier)

To Reproduce

I suspect the notification would show at https://play.grafana.org/a/grafana-lokiexplore-app/explore/service/opencost/logs?patterns=%5B%5D&from=now-2d&to=now&var-lineFormat=&var-ds=grafanacloud-logs&var-filters=service_name%7C%3D%7Copencost&var-fields=&var-levels=&var-metadata=&var-jsonFields=&var-patterns=&var-lineFilterV2=&var-lineFilters=&displayedFields=%5B%5D&urlColumns=%5B%5D&visualizationType=%22logs%22&var-labelBy=&timezone=utc&var-all-fields=&prettifyLogMessage=false&sortOrder=%22Descending%22&wrapLogMessage=false if there was more data/allowed to query on longer periods

Expected behavior

I don't want to battle this notification. I don't understand what I have done to make it trigger. I just want to read the logs without distractions like I was able to just some time ago :)
