### Electron Version

12.0.7

### What operating system are you using?

Ubuntu

### Operating System Version

5.4.0-73-generic #82~18.04.1-Ubuntu

### What arch are you using?

x64

### Last Known Working Electron version

_No response_

### 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).

### Testcase Gist URL

https://gist.github.com/gniezen/34950a5fa84dcf000e2b55a8d599ecd6

### Additional Information

To reproduce using gist:

- Replace `usbVendorId` and `usbProductId` with that of your test device.
- Click the `Connect` button. It should show up in the port list on the main console.
- Click the `Get Ports` button. It should show the existing permission in the developer console.
- Unplug and re-plug the device.
- Click the `Get Ports` button. It should show the existing permissions, but returns an empty list.
