Linux randomly enables and disables tablet mode on a Lenovo Thinkpad X1

I use a Lenovo Thinkpad X1 (Gen 6) laptop. Currently, I'm on Fedora. In the GRUB menu, the internal keyboard works as expected. While using the OS, the keyboard is mainly unresponsive, but sometimes gets enabled and directly after that disabled. This is what it looks like observed with libinput debug-events:

-event16  SWITCH_TOGGLE           +13.842s	switch tablet-mode state 0
-event15  SWITCH_TOGGLE           +13.843s	switch tablet-mode state 0
-event16  SWITCH_TOGGLE           +13.892s	switch tablet-mode state 1
-event15  SWITCH_TOGGLE           +13.892s	switch tablet-mode state 1

evtest shows what device those events are attached to:

/dev/input/event15:	ThinkPad Extra Buttons
/dev/input/event16:	Intel HID switches

libinput is on version 1.24.0. This problem occurs (at least) with the following distros: - OpenSUSE Tumbleweed - Vanilla OS Orchid - Arch - Fedora It would be best if I could make the tablet mode appear only when the laptop is "flipped", but completely disabling the tablet mode (or that the tablet mode disables the keyboard) is enough. --- I tried to disable it with:

export LIBINPUT_IGNORE_DEVICE="17 20"

I also tried disabling both events at the same time with:

evtest --grab /dev/input/event15
evtest --grab /dev/input/event16

Although libinput debug-events stopped reporting the tablet mode switching, it still occurred.
