An Issue Alert When Condition Doesn't Trigger Reliably

### Environment

SaaS (https://sentry.io/)

### Steps to Reproduce

1. Create an Issue Alert with conditions provided (screenshot)
2. Throw a couple of errors, one error every minute or so

### Expected Result

Alert should be triggered reliably by 1 event.

### Actual Result

Alert is sometimes not triggered by 1 event (the HttpException in this case). Instead it seems to only fire reliably for 2, 3, 4, 5 events in the 1 min interval.
