RFR: JDK-8298104: NPE on synchronizeSceneNodes()

Wed May 3 20:40:10 UTC 2023

A null pointer exception occurs on the ScenePulseListener when iterating through the dirty node list.
A null check is needed on the node before calling node.getScene().

The error occurs occasionally and causes the application to crash.
