Steps to reproduce

A non-advanced function (or script) by definition doesn't support common parameters.

Yet, if a non-advanced function has comment-based help, its syntax diagram shows [<CommonParameters>] - when invoked via -? or Get-Help (but not with Get-Command -Syntax) - mistakenly suggesting that they are supported:

function Get-Foo { <#.SYNOPSIS #> }; Get-Help Get-Foo
