WkWebView doesn't support WebSQL but it exposes window.openDatabase which breaks feature detection Remove window.openDatabase so that feature detection is once again reliable https://bugs.webkit.org/show_bug.cgi?id=137760
Retitling: WKWebView: don't expose openDatabase if WebSQL is disabled at runtime
This is related to https://bugs.webkit.org/show_bug.cgi?id=137760, but does not *depend* on it. This bug could be resolved today with any resolution of 137760. So I'm removing the dependency.
