…hit testing Summary: Native views use the AppKit api for hit testing which requires the point to be in the superview coordinate system. This diff updates the hit testing in `RCTViewComponentView` to conditionally converts the point to the target view coordinate system only if the tested view is a react view. Test Plan: Run Zeratul with Fabric and select text inside message bubbles. The scroll view being a native view, the hit testing does not require a point conversion. With this change, the text selection works as expected. | Before | After | |--| | https://pxl.cl/3Mlpb | https://pxl.cl/3MllN | Reviewers: shawndempsey, #rn-desktop Reviewed By: shawndempsey Differential Revision: https://phabricator.intern.facebook.com/D51129375 Tags: uikit-diff

This is part of a series of PRs where we are cherry-picking fixes from #2117 to update our Fabric implementation on macOS.
Summary:
Unlike UIKit, AppKit hit testing requires the point to be in the superview coordinate system. As such, we have to override hit testing in React Native macOS to match the assumed iOS semantics.
Followup change I made to the original commit: I removed the
RCTViewimport/check for hit testing inRCTViewComponentViewbecause I don't think we'll ever be moving paper and fabric views like that.Test Plan:
CI should pass, maybe also try picking 71fae19 and see if selection works now
