Describe the bug

Reordering the customRDPProperty field after successfully creating a host pool doesn't take affect if the same properties are defined. I originally observed this behaviour when dealing with Terraform, this is opened in
hashicorp/terraform-provider-azurerm#27071

Expected behavior

Order of the items is changed

Actual behavior

Property is not updated

Reproduction Steps

Step1: Create a host pool with value of customRdpProperty starting with audiocapturemode:i:1;audiomode:i:0;.
PUT /subscriptions/...resourceGroups/testRG/providers/Microsoft.DesktopVirtualization/hostPools/testpool?api-version=2022-02-10-preview HTTP/1.1
Request Body:

{
   "location":"eastus",
   "properties":{
      "customRdpProperty":"audiocapturemode:i:1;audiomode:i:0;camerastoredirect:s:*;redirectclipboard:i:1;redirectcomports:i:0;usbdevicestoredirect:s:;devicestoredirect:s:;drivestoredirect:s:*;redirectprinters:i:0;redirectsmartcards:i:0;encode redirected video capture:i:1;redirected video capture encoding quality:i:1;enablecredsspsupport:i:1;videoplaybackmode:i:1;redirectwebauthn:i:0;use multimon:i:1;",
      "description":"",
      "friendlyName":"test pool",
      "hostPoolType":"Personal",
      "loadBalancerType":"Persistent",
      "maxSessionLimit":999999,
      "personalDesktopAssignmentType":"Automatic",
      "preferredAppGroupType":"Desktop",

      "startVMOnConnect":false,
      "vmTemplate":"",
      "validationEnvironment":false
   },
   "tags":{
   }
}

Step2: Reorder the value of customRdpProperty property， update the host pool with value of customRdpProperty starting with audiomode:i:0;audiocapturemode:i:1;.
PATCH /subscriptions/.../resourceGroups/testRGproviders/Microsoft.DesktopVirtualization/hostPools/testpool?api-version=2022-02-10-preview HTTP/1.1
Request Body:

   }
}
