localForage: Safari 10 detection for indexedDB fails

(Desktop) Safari 9.1 detection for indexedDB seems to fail at this conditional:

        // We mimic PouchDB here; just UA test for Safari (which, as of
        // iOS 8/Yosemite, doesn't properly support IndexedDB).
        // IndexedDB support is broken and different from Blink's.
        // This is faster than the test case (and it's sync), so we just
        // do this. *SIGH*
        // http://bl.ocks.org/nolanlawson/raw/c83e9039edf2278047e9/
        //
        // We test for openDatabase because IE Mobile identifies itself
        // as Safari. Oh the lulz...
        if (typeof openDatabase !== 'undefined' && typeof navigator !== 'undefined' &&
            navigator.userAgent &&
            /Safari/.test(navigator.userAgent) && !/Chrome/.test(navigator.userAgent)) {
            return false;
        }

IndexedDB does work, but because it doesn’t pass this conditional it falls back to webSQL which doesn’t seem to work in my setup.
