title: Google maps taking a long time to render in ie11
body: <p>The attached HTML renders very quickly in Chrome and Mozzilla browsers.  If I try to load it in IE11 I get several timeout errors and after 30 seconds the map finally renders.</p>
  
  <p>I have tried all kinds of settings in IE11 with no luck.  When I run with developer tools on in debugger mode. I get the error 
  InvalidValueError:not a string  in the following function 3 times </p>
  
  <pre><code>function wf(a,b){return function(c){if(a(c))return c;throw qf(b||""+c);}}function xf(a){var b=arguments;return function(a){for(var d=[],e=0,f=b[H];e&lt;f;++e){var g=b[e];try{(g.Ff||g)(a)}catch(h){if(!(h instanceof pf))throw h;d[F](h.message);continue}return(g.then||g)(a)}throw qf(d[rd]("; and "));}}function yf(a,b){return function(c){return b(a(c))}}function zf(a){return function(b){return null==b?b:a(b)}}function Af(a){return function(b){if(b&amp;&amp;null!=b[a])return b;throw qf("no "+a+" property");}}

  <p>After hitting F5 to continue three times the MAP finally renders.</p>
  
  <p>Here is the HTML.</p>
