PowerShell console in Visual Studio Code is a case to reproduce the issue.

Relevant code snippets

enum GetAncestorFlags
{   
    GetParent = 1,
    GetRoot = 2,
    /// <summary>
    /// Retrieves the owned root window by walking the chain of parent and owner windows returned by GetParent.
    /// </summary>
    GetRootOwner = 3
}

/// <summary>
/// Retrieves the handle to the ancestor of the specified window.
/// </summary>
/// <param name="hwnd">A handle to the window whose ancestor is to be retrieved.
/// If this parameter is the desktop window, the function returns NULL. </param>
/// <param name="flags">The ancestor to be retrieved.</param>
/// <returns>The return value is the handle to the ancestor window.</returns>
[DllImport("user32.dll", ExactSpelling = true)]
static extern IntPtr GetAncestor(IntPtr hwnd, GetAncestorFlags flags);

[DllImport("kernel32.dll")]
static extern IntPtr GetConsoleWindow();

// This is your window handle!
public IntPtr GetConsoleOrTerminalWindow()
{
    IntPtr consoleHandle = GetConsoleWindow();
    IntPtr handle = GetAncestor(consoleHandle, GetAncestorFlags.GetRootOwner );
    
    return handle;
}

Expected behavior

WAM windows always popup on the front

Identity provider

Microsoft Entra ID (Work and School accounts and Personal Microsoft accounts)

Regression

No response

Solution and workarounds

The customers should look for the WAM popup very hard

The key point here is that the terminal window is hosted in VS Code.
