Performance Issues Triggering High Priority Alerts Despite All Being Low Priority

### Environment

SaaS (https://sentry.io/)

### Steps to Reproduce

Create an alert as the below:

Observe that performance issues that are low priority are triggering the alert:

As a workaround for now, the user has filtered by IF "The issue's category is equal to Error." Customer also reported that performance issues should appear in the alert preview.

Alert linked in Jira ticket.

### Expected Result

Low priority performance issues do not trigger a "Send a notification for high priority issues" and the alert preview include performance issues.

### Actual Result

Low priority performance issues are trigger a "Send a notification for high priority issues" and the alert preview does not include performance issues.
