Cannot use WindowsPackageCab without specifying a LogPath

[p0w3rsh3ll]

Steps to reproduce

I'm trying to install/uninstall a package and did not specify a logpath

Configuration Disable-NetFx3 {
Param(
    [string]$NodeName = 'localhost'
)
    Import-DscResource -ModuleName 'PSDscResources'
    Node $NodeName
    {
        WindowsPackageCab 'NetFx3'
        {
            Name = 'Microsoft-Windows-NetFx3-OnDemand-Package~31bf3856ad364e35~amd64~~10.0.16299.15'
            Ensure = 'Absent'
            SourcePath = 'c:\mount\sources\sxs\microsoft-windows-netfx3-ondemand-package.cab'
            # LogPath = 'C:\dism.log'
        }
    }
}

if (-not(test-path -Path  C:\DSC -PathType Container)) {
    $null = mkdir  C:\DSC
}
Disable-NetFx3 -OutputPath  C:\DSC -Verbose
Start-DscConfiguration -Path  C:\DSC -ComputerName localhost -Verbose -Force -Wait

Configuration Enable-NetFx3 {
Param(
    [string]$NodeName = 'localhost'
)
    Import-DscResource -ModuleName 'PSDscResources'
    Node $NodeName
    {
        WindowsPackageCab 'NetFx3'
        {
            Name = 'Microsoft-Windows-NetFx3-OnDemand-Package~31bf3856ad364e35~amd64~~10.0.16299.15'
            Ensure = 'Present'
            SourcePath = 'c:\mount\sources\sxs\microsoft-windows-netfx3-ondemand-package.cab'
            # LogPath = 'C:\dism.log'

        }
    }
}
Enable-NetFx3 -OutputPath  C:\DSC -Verbose
Start-DscConfiguration -Path  C:\DSC -ComputerName localhost -Verbose -Force -Wait

The above configurations work if I uncomment the logpath and use the one specified (c:\dism.log).

Expected behavior

I should be able to install/uninstall without specifying a logpath.
It's not a mandatory parameter and its help descriptions says:

There is no default value, but if not set, the log will appear at %WINDIR%\Logs\Dism\dism.log.

Actual behavior

If the Set-TargetResource is invoked, it throws:

VERBOSE: [mycomputer]: LCM:  [ End    Set      ]  [[WindowsPackageCab]NetFx3]  in 0.0630 seconds.
PowerShell DSC resource MSFT_WindowsPackageCab  failed to execute Set-TargetResource functionality with error message: DismInitialize failed. Error code = 0x80070057
