Bug ID: 197773
Summary: [GTK] Touchscreen detection false positive
Product: WebKit
Version: Other
Hardware: PC
OS: Linux
Status: NEW
Keywords: Gtk
Severity: Normal
Priority: P3
Component: WebKitGTK
Assignee: webkit-unassigned at lists.webkit.org
Reporter: hi at ryandebeasi.com

WebKitGTK is detecting a touch screen on my device, even though I don't have a touch screen. I'm not seeing this behavior on Firefox or Chrome. I'm running GNOME Web 3.28.1 on Elementary OS Juno (Ubuntu 18.04.2 LTS) on a Dell XPS 13 (9343).
To reproduce:
1. Open GNOME Web on a device that does not have a touchscreen.
2. Open the browser developer tools.
3. Go to Console.
4. Type `window.matchMedia("(any-pointer:coarse)").matches`.
5. `true` appears.
Following the same steps in Firefox or Chrome produces `false`.
Alternately, this page also reproduces the problem: https://patrickhlauke.github.io/touch/touchscreen-detection/
