All reviewed patches have been landed. Closing bug.
The LayoutTest for this change is failing on iOS: https://build.webkit.org/results/Apple%20iOS%2010%20Simulator%20Release%20WK2%20(Tests)/r213099%20(4127)/results.html It looks like ios-sim EWS caught this before the patch as landed.
Thanks Ryan, I'll fix this once I'm done building iOS.
Reopening to attach new patch.
