Currently PointerEvent.pointerId is used to build DeviceId, however this isn't perfect because the same device can get a new ID when it is disabled during a session. E.g. your mouse is plugged and the unplugged: it will get a new DeviceId. This is especially bad for non-connected (battery-free) pens, which get a new DeviceIdevery time they leave the maximum hover distance.
For this reason a new PointerEvent.persistentDeviceId was introduced, which identifies a specific device by a unique device ID throughout the whole session.
This is supported by default on Chrome since v128.
