It works for me on 1.6.0 (client is Windows 10 with Chrome). Without being in full screen, Alt+Tab opens my local Windows app switcher. In full screen, it goes through to the remote computer.
Which makes sense, Alt+Tab is also captured by this demo https://codepen.io/Weston-Thayer/pen/JoGvBym?editors=0010 which you can use to probe other browsers to understand what can and can't be captured.
