Expected Behavior
const existingPermissions = await navigator.serial.getPorts(); should return a list of serial ports for which permission has already been granted, even when a device has been unplugged and plugged back in again.
Actual Behavior
The list is empty, even when the same code works in the browser (Chromium v90.0.4430.93).
