Comment on attachment 395872 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=395872&action=review > Source/WebCore/platform/cocoa/ScrollController.mm:107 > + // FIXME: Trying to decide if a gesture is horizontal or vertical at the "began" phase is very error-prone. This likely wants something more like a generalized VGC::PendingSwipeTracker
