动态参数输入后未显示静态验证集参数

Question

我使用动态和静态参数的混合发现了以下情况，我想知道我做错了什么，或者是否存在面对这种情况的自动完成的错误/意外行为。

我有两个功能。

Test-MyExampleSet -Service 'Service 1' # Auto-Completion does not suggest -Name parameter

Test-MyExample -Service 'Service 1' -Name AdminTools # Auto-completion works fine.

第一个使用validateset和动态参数的静态参数。

第二个具有静态参数（字符串）和dynamyc参数。 使用Test-MyExampleSet时，在添加-Service参数后，自动完成不会在任何位置显示-Name动态参数。

使用Test-MyExample重复完全相同的事情，这与减去验证集完全相同，可以正常工作。

是否与我声明动态参数的方式有关，还是混合动态参数和静态参数确实存在问题？

包含2个函数定义的示例代码

$include = @("Service 1", "Service 2")

function Test-MyExample

[cmdletBinding()]

  (
    [Parameter(Position=-0,Mandatory=$false)]

Test-MyExampleSet -Service 'Service 1' # Auto-Completion does not suggest -Name parameter

Test-MyExample -Service 'Service 1' -Name AdminTools # Auto-completion works fine.
