title: all values to one key in localStorage was missing
body: <p>I stored two keys with some values as JSONObject like </p>
  
  <pre><code> var A = [];
   var B = [];
  
   var objForA = {};
   objForA.a  = a;
   objForA.b  = b;
   objForA.c  = c;
   .... 
  
   A.push(objForA);
  
   var objForB = {};
   objForB.a  = a;
   objForB.b  = b;
   objForB.c  = c;
   .... 
   A.push(objForB);
  
     localStorage.setItem('A',JSON.stringify(A));
  
     localStorage.setItem('B',JSON.stringify(B));
  </code></pre>
  
  <p>There is no problem when I get the data in a day, However I have problem when I delete Cache,History,Cookie, etc... when I get the property of localStorage, I only have values to one key, which name of key is B.
  The thing that I'm wondering is why only one key's values was missing.. </p>
  
  <p>I thought so many times and tried to find the difference between the way I stored A and B... but .. there's nothing different.</p>
  
  <p>when I did console.log , It was looking like</p>
  
  <pre><code>A: []
  </code></pre>
  
  <p>I don't know why this values was missing ...... the number of data in A twice of 
  data in B. Is it not okay to store a lot of data using localStorage? </p>
  
  <p>How can I figure out the reason ? </p>
  
  <p>Thank you. </p>
