Azure App Configuration: Issues Overriding Non-Prefixed Keys with Prefixed Variants

Question

Given an Azure App Configuration key with no prefix: Setting123, I am not able to override this key with a prefixed version of it Environment:Setting123.

This returns the key with the value from the non-prefixed key. If I don't execute TrimKeyPrefix then I see both values in the built config:

config.AddAzureAppConfiguration(options =>{    
options.Connect(new Uri(url), token)        
.Select(KeyFilter.Any)    
.Select($"{environment}:*").TrimKeyPrefix($"{environment}:");
});

If I add a prefix to the non-prefixed key, then the last one added takes precedence as expected:

config.AddAzureAppConfiguration(options =>{    
options.Connect(new Uri(url), token)        
.Select($"{commonPrefix}*").TrimKeyPrefix($"{commonPrefix}")    
.Select($"{environment}:*").TrimKeyPrefix($"{environment}:");
});

I'm seeking clarification as to if this is intended. I wasn't able to find any documentation that stated explicitly either way, but would expect it to have been called out if you are unable to override a non-prefixed key with a prefixed one.

Perhaps there are best practices that I am unaware of, would appreciate any guidance or input.
