title: Why is it that LoadParams.requestedLoadSize returns the specified page size to LivePagedListBuilder times 3?
body: <p>I am creating a <code>PagedList</code> using:</p>
  
  <p><code>LivePagedListBuilder(dataSourceFactory, 20)</code></p>
  
  <p>Inside my implementation of <code>PageKeyedDataSource</code>, <code>loadParams.requestedLoadSize</code> returns 60. I tried with other numbers, and it seems that <code>loadParams.requestedLoadSize</code> always returns the page size I specified times three.</p>
  
  <p>Anyone has any idea as to why this is happening?</p>
