Intellisense not working with local functions, no synopsis or function details shown.

Issue Description

When writing powershell scripts intellisense seems to not be working. Given the following example powershell script:

# On this line, remove this comment and type: Start-A10-Session and hit Ctrl+Space and you will see it doesn't give any details about the Start-A10-Session function

function Start-A10-Session {
    Param
    ( 
        [String]
        # A10 DNS Name
        $A10Device,
        [String]
        # User Name
        $Username,
        [String]
        # Password        
        $Password
    )

    $body = '{"credentials":[{"username":"' + $UserName + '", "password":"' + $Password + '" }]}'
   
    Write-Host $body
    
    $response = Invoke-RestMethod -Uri "https://$A10Device/axapi/v3/auth" -Method 'Post' -Body $body -ContentType 'application/json'
    
    Write-Host "Opened SessionID =  $response.authresponse.signature"
    return $response.authresponse.signature

        <#
        .SYNOPSIS
        This is a test powershell script
...
    #>
}

When you start to type Start-A10-Session all you see is this:

No parameters are listed, and the synopsis information is missing.

Thanks @xantari looks like intellisense is failing completely, I will mark this as a duplicate of #2745
