Source/WebCore:
They are calling scrollHeight on the HTML element and it is running new code introduced in r235806
Disable this new feature until they update their app to use the iOS13 SDK.

Source/WebKit:
Change the CSSOMViewScrollingAPIEnabled default value to be off for the IMDb app's WKWebViews.
I manually verified this is effective in those WKWebViews but no other WKWebViews and that it fixes the radar.
