az webapp snapshot restore not working with paired region target

[cberon-alliant]

Describe the bug

az webapp config snapshot restore is returning error "no resource group found" when trying to restore a snapshot backup to a paired region. This is required for DR scenarios, and is supported and working properly via Restore-AzWebAppSnapshot.

Steps
Using the cloud shell, create a rg in east us2, a webapp, and enable snapshot backups.

$sourceRg = 'app-rg'
$sourcePlanName = 'app-plan'
$sourceAppName = 'app-web'

$recoveryRegion = 'centralus'
$targetRg = "$($sourceRg)-dr"
$targetPlanName = "$($sourcePlanName)-dr"

az group create --name $targetRg --location $recoveryRegion

$sku = az appservice plan show --name $sourcePlanName --resource-group $sourceRg --query "sku.name" -o tsv

az appservice plan create --name $targetPlanName --resource-group $targetRg --location $recoveryRegion --sku $sku

$targetAppName = "$($sourceAppName)-dr"
az webapp create --name $targetAppName --plan $targetPlanName --resource-group $targetRg

restore the most recent snapshot

$snapshots = az webapp config snapshot list --name $sourceAppName --resource-group $sourceRg | ConvertFrom-Json -DateKind String
az webapp config snapshot restore -g $targetRg -n $targetAppName --source-name $sourceAppName --source-resource-group $sourceRg --time $snapshots[0].time --debug

BUG:
Portal returns error: Operation returned an invalid status 'Not Found'

EXPECTED:
No error, and snapshot is restored to target Web App

Related command

az webapp config snapshot restore -g $targetRg -n $targetAppName --source-name $sourceAppName --source-resource-group $sourceRg --time $snapshots[0].time

Errors

Operation returned an invalid status 'Not Found'
