    `localStorage.setItem` can overwrite `localStorage` methods · 3868bff6

    Update the JSC and V8 bindings such that if the name of the DOM
    Storage property being retrieved is a match for a property in the
    prototype, always return the prototype version. If there is a DOM
    Storage key of the same name, it can still be retrieved via the
    getItem method. This prevents storage methods from being
    accidentally hidden. This brings WebKit behavior in line with the
    de facto standard implemented by FireFox and IE.

    being called, but also that it can still be retrieved via the getItem
