Get-AzDiagnosticSettingCategory returns categories, but the type doesn't support Diagnostic Settings

[rpstester]

Description

Get-AzDiagnosticSettingCategory is supposed to "List supported diagnostic setting categories."

When I run it against certain types, it returns one/more categories, but when I try to create with New-AzDiagnosticSetting, it fails saying "the resource type does not support diagnostic settings".

Why am I getting mixed messages? Can the Get command be updated to not return an unsupported category, please?
