zip_temp_layer sometimes stops working. I think the cause is that input_processor_temp_layer.c is not thread-safe. CONFIG_INPUT_MODE_THREAD is Zephyr's default, but is the pointing subsystem supposed to use CONFIG_INPUT_MODE_SYNCHRONOUS and the input driver to use the system thread?

my configuration:

Just in case it serves as another useful data point, I think that this comment sheds some light on the actual problem: #2729 (comment) for me a consistent repro is invoking a &to some-layer behavior while the temp layer is active and has not yet been disabled due to the timer, it causes the temp layer to never be enabled again and requires a keyboard reset.
