All,As a heads-up, we plan to push an updated WebKit to FX 9-dev [1] this coming week. It is targeted to go into the jdk-9+150 promoted build. We plan to backport the newer WebKit to 8u-dev (to keep them in sync) the following week.
Let me know if you have any questions. -- Kevin [1] https://bugs.openjdk.java.net/browse/JDK-8166999
