Get-AzCloudServicePublicIPAddress returning nothing despite being visible from portal and other commands

### Description

I have a Cloud Service (Extended Support) on Azure and want to retrieve the associated public IP address from an Azure script. However when I run
```
Get-AzCloudServicePublicIPAddress -CloudServiceName $serviceName -ResourceGroupName $resourceGroup -verbose
```
Nothing seems to happen at all.

Moreover, when I run a swap command, i.e.
```
Switch-AzCloudService -CloudServiceName $serviceName -ResourceGroupName $resourceGroup -Confirm:$
```
it is successful and I can see the public IP address for both the services in the output logging! Obviously I don't want to have to call this command to retrieve the IP address information. Surely something is wrong with the `Az.CloudService` module here?

Start at the Get-AzCloudServicePublicIPAddress entry point and inspect its request to the Microsoft.Compute cloudServices publicipaddresses endpoint, then compare it with the public IP information shown by Switch-AzCloudService. Done means the cmdlet returns the associated public IP address instead of an empty value for the reported Cloud Service (Extended Support) case.
