GNOME Web from flathub prints this in logs and crashes: ``` /usr/include/c++/12.2.0/optional:477: constexpr _Tp& std::_Optional_base_impl<_Tp, _Dp>::_M_get() [with _Tp = MotionEvent; _Dp = std::_Optional_base<MotionEvent, true, true>]: Assertion 'this->_M_is_engaged()' failed. ``` this usually happens during session restore, but can also happen during usage.

Problem is it's possible for a pointer leave event to occur before any pointer motion event. I thought that was not possible. This is a regression in 2.40.2.
