"validations.kong.konghq.com" denied the request: consumer already exists error in isolated namespaces

Kong version ($ kong version)

Kong 3.1

Current Behavior

In our environment we have deployed the same consumers in different namespaces. This has previously worked before but recently we were doing changes around our Kong consumers and on adding new environments we are getting the following error:
one or more objects failed to apply, reason: admission webhook "validations.kong.konghq.com" denied the request: consumer already exists

Kong logs that are probably related:

time="2024-09-17T09:30:18Z" level=error msg="failed to run validation" component=admission-server error="unique key constraint violated for key"

We are aware of the documentation that mentions username should be unique but this method of isolation has worked before and should probably continue to do so. Our environments should be a easily reproducible as possible.
