            Bug ID: 261674
           Summary: [GTK4] NativeWebWheelEvent crashes on wheel event
                    tests
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified

In the gtk4 port, at least these tests are crashing due to a GdkEvent not being such:

fast/scrolling/gtk/repeated-mouse-wheel-smooth.html
fast/repaint/overflow-auto-in-overflow-auto-scrolled.html

fast/events/wheel/continuous-platform-wheelevent-in-scrolling-div.html

The common stacktrace:

#0  g_logv (log_domain=0x7f6df60f0917 "Gdk", log_level=G_LOG_LEVEL_CRITICAL, format=<optimized out>, args=<optimized out>) at ../glib/gmessages.c:1422

Looks like some #ifdef'ing is missing for the GTK4 port, as GdkEvent usage has changed since GTK3. I'll look into it.
