Scope "managementGroup" is not valid for this module. Permitted scopes: "resourceGroup".bicep(BCP134)

[Ex3mXX]

Bicep version
VS Code v0.5.6

Describe the bug
When using 'Microsoft.Authorization/policyExemptions@2020-07-01-preview' as a module the Scope options can't be set to ManagementGroup.

To Reproduce
main.bicep

targetScope = 'managementGroup'
// POLICY EXEMPTIONS MODULE
module exemptions './exemptions.bicep' = {
  name: 'exemptions'
}

exemptions.bicep

// RESOURCES
resource exemption_1 'Microsoft.Authorization/policyExemptions@2020-07-01-preview' = {
  name: 'exemption_1'
   properties:{
     exemptionCategory: 'Waiver'
     policyAssignmentId: 'someId'
   }
}

Additional context
When not using module it works without scope, and when using module it only accept resource group as scope.

The targetScope is not inherited, so you need to declare targetScope = 'managementGroup' in exemptions.bicep as well.

targetScope = 'managementGroup'

// RESOURCES
resource exemption_1 'Microsoft.Authorization/policyExemptions@2020-07-01-preview' = {
  name: 'exemption_1'
   properties:{
     exemptionCategory: 'Waiver'
     policyAssignmentId: 'someId'
   }
}
