AVD with AzureAD-joined VMs: bug?

Hi, 

I setup a test environment for AVD with Azure AD-joined VMs.

I wanted to try the FSlogix file share with Azure AD as an identity provider.

I followed the steps in this procedure to try and connect to an AVD configuring the host pool's RDP Properties (my computer was not part of the Azure AD tenant): https://learn.microsoft.com/en-us/azure/virtual-desktop/azure-ad-joined-session-hosts#access-azure-ad-joined-vms

"If your local PC doesn't meet one of these conditions, add targetisaadjoined:i:1 as a https://learn.microsoft.com/en-us/azure/virtual-desktop/customize-rdp-properties to the host pool. These connections are restricted to entering user name and password credentials when signing in to the session host."

It works but every time I connect, the RDP properties are modified and the targetisaadjoined:i:1 parameter goes to the very beginning of the parameters. 

When the parameter is located here, I can't connect anymore and I receive an error message:

I must set the parameter at the end again to be able to connect properly.

Is there a but here?

For the record, I'm running on a trial M365 Business Premium license.

Thanks for your feedback guys!
