Alerts not triggered for empty environment value

[InterstellarStella]

Environment

SaaS (https://sentry.io/)

Steps to Reproduce

Set up an issue alert with the conditon:

If all of these filters match:
The event's environment value is not set

Then send an event that does not have an environment value.

Expected Result

This event triggers the alert.

Actual Result

The event does not trigger the alert. Links to such events are provided in the shadow ticket.

The workaround for now is to set the alert condition as:

If all of these filters match:
The event's environment value not in (comma separated) existing,environment,values

Thanks for filing @InterstellarStella - can you share more about the use case/ intent behind this alert, i.e. why would an event not have an environment?
