Internet explorer 11 console.log random / unreliable output

I just created an index.html file with the following content:

<script type="text/javascript">
    var markers = [{'dist': 1}, {'dist': 2}, {'dist': 3}];
    console.log(markers);
</script>

      

        
        
        
      

    

When the console is open (press F12 and select "Console") and just try refreshing the page a few times. The result should be the same as inside dynamic content, but it isn't.

I usually see this:

File: test.html, Line: 1, Column: 1
[object Object],[object Object],[object Object]
   [
      0: {
         [functions]: ,
         __proto__: { },
         dist: 1
      },
      1: {
         [functions]: ,
         __proto__: { },
         dist: 2
      },
      2: {
         [functions]: ,
         __proto__: { },
         dist: 3
      },
      length: 3
   ]

      

        
        
        
      

    

but sometimes it is:

File: test.html, Line: 1, Column: 1
[object Object],[object Object],[object Object]
   [
      0: {
         undefined: undefined
      },
      1: {
         undefined: undefined
      },
      2: {
         undefined: undefined
      },
      length: 3
   ]

      

        
        
        
      

    

Thanks in advance if anyone can shed some light on it.
