PowerShell module 2.x does not respect environment parameter - doesn't receive environment variables passed through

Given a simple manifest exec { 'test envvars': command => 'Write-Output "TESTVALUE = $env:TESTVALUE"', provider => powershell, logoutput => true, environment => ["TESTVALUE=YES"], } The output should be Notice: /Stage[main]/Exec[test envvars]/returns: TESTVALUE = YES {no format}   Conversely, given a simple manifest a second run will not have the env variable set in the first run:   {code} exec { 'test envvars': command => 'Write-Output "TESTVALUE = $env:TESTVALUE"', provider => powershell, logoutput => true, environment => ["TESTVALUE=YES"], } exec { 'test envvars': command => 'Write-Output "TESTVALUE = $env:TESTVALUE"', provider => powershell, logoutput => true, } {code}   The output in the first run should be Notice: /Stage [main] /Exec [test envvars] /returns: TESTVALUE = YES {no format} The output in the second run should be   Notice: /Stage [main] /Exec [test envvars] /returns: TESTVALUE ={no format}
