Assertion in GtkGestureRotate

Steps to reproduce

1. Use GtkGestureRotate
2. Rotate the view on a touchscreen (doesn't seem to happen on a trackpad)
3. Gdk-CRITICAL **: 19:02:17.172: gdk_touchpad_event_get_gesture_phase: assertion 'GDK_IS_EVENT_TYPE (event, GDK_TOUCHPAD_PINCH) || GDK_IS_EVENT_TYPE (event, GDK_TOUCHPAD_SWIPE)' failed
4. Everything still works despite the warning

Version information

GTK 4.3.2, org.gnome.Platform master

Additional information

This looks like it's analogous to #2825 (closed). If so, the issue is at gtk/gtkgesturerotate.c:98.
