Draft: Upper trackpad region thumb detection
Thumb detection for the upper region of the trackpad.
Here's the story. I recently bought a new laptop (T14s AMD gen3) with pretty shallow keys. I use the touchpad buttons quite often (located just above the trackpad!), and with the shallower trackpad buttons, my thumb is detected as a pointer movement every now and then.
Proposed solution: copy the thumb detection areas to the top as well.
