You can also get around it, at least in Chrome, by going to the console and entering:

  $('div#storytextp.storytextp').css('-webkit-user-select', 'inherit');

If that doesn't work, I would also try:

  $('div.nocopy').removeClass('nocopy');

I have no idea what the 'nocopy' class actually does (in Chrome it seems to do nothing), but it seems like something to try.
