Comment on attachment 373290 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=373290&action=review > Source/WebKit/UIProcess/API/Cocoa/WKWebView.mm:2029 > + [_scrollView _setScrollEnabledInternal:_page->scrollingCoordinatorProxy()->hasScrollableMainFrame() || hasDockedInputView || isZoomed || [_scrollView _hasContentInRelevantInsetAreas]]; I'm working on a change that will make this scrollable if the visualViewport is smaller than the layoutViewport. Does that help in this case?

Does that help in this case? It might happen to fix rdar://problem/50822146 by accident, but in general I don't think so. This is about scrolling to items positioned outside of our content view.
