title: Can't create IndexedDB database in IE10
body: <p>I write codes to create database:</p>
  
  <pre><code>var db;
  var request = indexedDB.open("TestDatabase");
  request.onerror = function(evt) {
    console.log("Database error code: " + evt.target.errorCode);
  };
  request.onsuccess = function(evt) {
    db = request.result;
    console.log(JSON.stringify(db));
  };
  </code></pre>
  
  <p>It runs fine in FF/Chrome, the code: JSON.stringify(db) returns json object.
  But, it doesn't work in IE10. The code: JSON.stringify(db) returns an empty object.</p>
  
  <p>Do everybody have the same problem? Could you spent your time to help me please? Thanks. </p>
  
  <p>Update: I also checked IndexedDB supported in IE10, like it:</p>
  
  <pre><code>var indexedDB = window.indexedDB || window.webkitIndexedDB || window.mozIndexedDB || window.msIndexedDB;
  </code></pre>
  
  <p>It returns true! I don't know JSON.stringify(db) always returns an empty object. :(</p>
