WontFix now that iOS10 is dropped.

This bug is about removing the code and the code is still there. Justin, I'm I missing something?

Woops, we removed a reference to this in ios/chrome, but it's still in ios/web (as expected since it supports iOS10).

Thanks for catching this, sorry for incorrectly closing.

The NextAction date has arrived: 2018-12-01

ios/web still supports iOS10
