[Webkit-unassigned] [Bug 139681] Touch support is reported even when the device doesn't have a touch screen

--- Comment #22 from Ryan DeBeasi <hi at ryandebeasi.com> ---
My understanding is if a device has both a touch screen and a mouse, reporting support for touch events is valid behavior. So, I think option A would be a totally reasonable course of action.

For more granular touch/mouse checks, web developers can check for the `pointer` CSS media feature. CSS media queries for the pointer also return some inaccurate results on WebKit GTK+ - see Bug 197773.

Thank you so much for your time!
