Additional context

WhatIf should not output parameter like size
Noisy parameters:

• properties.size

[dj-r1]

properties.size is returned in Azure REST API (Firewall Policies - Get) and also shown in example firewallPolicy.json (Azure REST API Specifications), so I think WhatIf operation would need to suppress it.
