I believe I have addressed the reviews. I am not entirely satisfied with the tests, as I would have preferred to also test that the driver setting no ContainerID leads to no error. But adding such tests turns out to be much more complicated than I expected due to the event order tracking in tests/driver_pnp.c that would need to be changed to accommodate 2 devices, since keeping the overall logic would require `IOCTL_WINETEST_CHILD_CHECK_REMOVED` to actually work.
