title: Does document.execCommand('copy') have a size limitation?
body: <p>I am using document.execCommand('copy') similar to what is described here:</p>

  <p>In my case, I'm placing data from a Kendo grid into a hidden textarea to be copied.  Somewhere between 2500 and 3000 rows, or around 350k of data, the copy fails.</p>
  
  <p>I've unhidden the textarea to make sure it's getting the full contents of the grid, and that is working.  I can copy all 3000+ rows manually from the visible textarea.</p>
  
  <p>But document.execCommand fails to copy it.  Is there some size limitation I'm reaching?</p>
