Public bug reported:

In the "Mouse and Touchpad" application, "Disable touchpad while typing"
is ticked - however, this seems to have no effect.  Catching the
trackpad whilst typing sends the cursor ricocheting across the screen.

Expected behaviour:
"Disable touchpad while typing" does indeed disable the touchpad within {x} seconds of a key-press occurring - or, if this functionality isn't available with this hardware, the option should be greyed-out/disabled.

Actual behaviour:
The "Disable touchpad while typing" check-box seems to have no effect on the system - there is no noticeable change of behaviour no matter what the state of the control.
