Syntax block is not generated in HTML sometimes

[dermeister0]

Test1 module:

function Invoke-TestCmdlet
{
    param
    (
        [Parameter(Mandatory = $true, HelpMessage = 'Only test.')]
        [string] $Path
    )
}

.\psDoc.ps1 Test1 -template .\out-html-template.ps1 -fileName Test1.html

.\psDoc.ps1 Test1 -template .\out-markdown-template.ps1 -fileName Test1.md
http://screencast.com/t/6Wi2v7V0kR

It happens, because the block is ignored in out-html-template.ps1:

if (!($_.syntax | Out-String ).Trim().Contains('syntaxItem')) {

However, the Markdown implementation works fine.
