Deployment never completes when deploying bicep file in mode "Complete"

> ### `az feedback` auto-generates most of the information requested below, as of CLI version 2.0.62

**Describe the bug**

When using **az deployment group create** command to deploy using a bicep file, the deployment never completes even when all internal bicep modules deployed successfully, it always displays as in progress in the azure portal and as running in the cli
**To Reproduce**

1. Create a simple bicep file that uses other bicep files as modules
2. Run the command similarly as follow:
az deployment group create --subscription "My subscription" --resource-group "MyRg" --parameters env='Dev --template-file main.bicep --mode Complete

**Expected behavior**

Once all the modules that are defined inside main.bicep successfully completes, the main deployment should be marked as completed as well. This has been specially annoying since we need to make sure that if we remove a data factory child from the bicep templates, it should get removed when deploying to azure.

**Environment summary**

az cli version 2.27.2
**Additional context**

This is how it usually looks, in the image i had to cancel it as it passed a really long time still in progress

And this is how the details of the main deployments look, all the underlying resources deployed aka internal bicep modules deployed fine but the main deployment never completed.
