on touchpad, two fingers always prevents tracking

I've configured my touchpad for two-finger scrolling in Gnome, but I've noticed that it behaves a bit different than the touchpad on my other machine, a MacBook running Mac OS.  On my Mac, if I start tracking with one finger but accidentally brush the trackpad with a second finger or palm on accident, the device continues tracking with my first finger and ignores the second finger.  In Gnome, once I touch two fingers to the trackpad all tracking stops.  I can scroll if I slide both fingers, but if I slide only one nothing happens at all...the pointer doesn't move.

Is there a way to get the Mac OS behavior under Gnome, where slight brushes against the trackpad with the palm or another finger don't interrupt the first finger's tracking?  I poked around:

I tried futzing with PalmDetect and related properties, and PalmDetect does appear to work, but is different from what I'm trying to do.

Does anyone know if the behavior I'm trying to get is possible?
