I can see this effect on Debian on kernel 5.10.0-9, and its also a Lenovo Yoga device, a Yoga 12.
Also, I've noticed that the messages disappear when the thinkpad_acpi kernel module is unloaded.
See this unload/load cycle:

Not sure if this is important, but I also have the tp-smapi-dkms package installed.
