Pull Secret creation fails with Azure Container Registry when using az cli for login

What happened?
When using recommended login to Azure Container Registry:

az login
az acr login -n <registry>

the entry in .docker/config.json is not accepted by devspace when using the Pull Secrets capability.

Running

devspace deploy

does not create a pull-secret. After printing "Ensuring image pull secret for registry:", the create part never happens.

If we instead use the Azure Container Registry admin account for login:

docker login <acr> --username <adminaccount>--password <passord>

This works as expected when deploying with devspace:

pullsecret:helsenorge Ensuring image pull secret for registry: 
pullsecret:helsenorge Created image pull secret dev/devspace-pull-secrets

The difference between the .docker/config.json az acr login:

{
    "auths": {
        "<>.azurecr.io": {
            "auth": "...",
            "identitytoken":"..."
        }
    }
}

docker login with admin account

{
    "auths": {
        "<>.azurecr.io": {
            "auth": "..."
        }
    }
}

What did you expect to happen instead?
Logging in with az acr login with your private account should work in the same way as logging in with an admin account. It should atleast give a clear error message about why the secret was not created.

How can we reproduce the bug? (as minimally and precisely as possible)

Use acr as container registry and login to this with az acr login
Setup pull-secret in devspac.yaml targeting acr
Run devspace deploy and see that no "devspace-pull-secrets" is created and no error messages are printed.

My devspace.yaml:

pullSecrets:
  helsenorge:
    registry: <>.azurecr.io
