Invoke-UDJavascript Returns null Unexpectedly

[parzog]

Description of Issue

Reference forum post #11799 - When attempting to run Invoke-UDJavascript without user interaction to return a value (such as using window.localStorage.theme to retrieve the current user's dark/light mode selection) returns null instead of the value expected. The output is correct when ran with user interaction, such as the following:

New-UDApp -Content {
    New-UDButton -Text "h" -OnClick {
        Show-UDToast -Duration 10000 (Invoke-UDJavascript -Javascript "window.localStorage.theme")
    }
}
