The search entry in the locationbar gained a clear button, but the clear button should only be visible when the entry is non-empty. Right now the italicized search engine hint is enough to trigger the "non-empty" state and show the button; this should be handled for so that the clear button is only visible if real text is present to avoid confusion. This also matches behavior of other entries in the browser, e.g. search widgets in pages and the findbar.
