Touch-screen input area spreads to non-touch screens

Xorg log including evdev output and hot plug of second screen
Description of problem: When a device with a touchscreen is attached to a non-touch capable screen, the width of the touchscreen is extended out to the edge of the non-touch-capable device
Version-Release number of selected component (if applicable): 2.8.0-1.fc19.x86_64
How reproducible: always
Steps to Reproduce:
1. Attach a second screen to a laptop/tablet with a touch screen
Moving a pointer along the touchscreen horizontally causes the pointer to continue past the edge of the touchscreen and across the non-touch screen
Moving the pointer with the touchscreen should stop at the edge of the touchscreen
[ 82736.865] (II) XINPUT: Adding extended input device "Atmel Atmel maXTouch Digitizer" (type: TOUCHSCREEN, id 9)
Using a Dell XPS12, and an additional screen connected via Mini DisplayPort
device is type TOUCHSCREEN, but the actual binding to a single screen needs to be done by the client stack, i.e. gnome-settings-daemon on the default desktop.
Reassigning, I don't know off-heart if this is being implemented yet. it works on those devices supported by libwacom, but it's not yet generic and I suspect this device simply falls out of that set.
In any case, Sten, please record the device with evemu and attach the recordings here.

No events were recorded when the external monitor was plugged in (as is expected, since this is not an ev event)

This message is a notice that Fedora 19 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 19. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 19 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
