If you put this on WKWebView instead you can avoid the pageclient hits AND avoid expanding the C API.

This is causing crashes on three ios-wk2 tests in EWS and on build.webkit.org:

swipe/main-frame-pinning-requirement.html
swipe/pushState-programmatic-back-while-swiping-crash.html
webgl/1.0.3/conformance/ogles/GL/lessThan/lessThan_001_to_008.html

Example test run:  <https://build.webkit.org/results/Apple%20iOS%2013%20Simulator%20Release%20WK2%20(Tests)/r259848%20(3630)/results.html>

BTW, this looks kind of like a use after free based on the crash logs.

iOS WK2 EWS is so slow that I can't wait for it.
