JSObject::hasOwnProperty() should use getOwnPropertyDescriptor() rather than getOwnPropertySlot(), since getOwnPropertySlot() does proxying of prototype properties; this is an implementation detail that shouldn't be exposed through public JS functions. 1885787 1 ahmad.saleem792 2022-07-21 13:30:23 -0700 All dependent bugs are fixed and Safari pass all WPT related test for this: https://wpt.fyi/results/js/builtins?label=master&label=experimental&aligned&q=object.prototype.hasownproperty Is something needed more here?
