HEADS-UP: plan to integrate a newer WebKit into 9-dev next week

[Kevin Rushforth]

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.
