WebCore cannot link UIKit.
Comment 13 Tim Horton 2021-05-19 10:10:27 PDT 
(The correct layering would see you delegate this to WebKit and implement it there, but WebKitLegacy can’t link UIKit either so you’d have to further delegate out to UIKit in the WebKitLegacy case.)

Thanks for reviewing!

I think we have to use upward linking to solve this, but we have to do it for all UIKit symbols used in WebCore.
