Back port the fix related to stylus bug on Gnome Wayland

Hello team, I filed a bug report[1] related to the stylus crashing applications on the default Gnome Wayland session on Fedora 31 Workstation. At the time of writing, bugzilla is currently down thus unable to link the report. It turned out upstream already fixed the issue [2] and it will be nice to back port it after the Fedora 31 release.
