   5     /* Need to float the first letter, to turn it into a block. Otherwise, overflow-y wouldn't be
   6        an applicable property in the first place. */

   9 <p>overflow-y isn't a valid property for ::first-letter. We'd crash when extracting innerText,
  10     because the implementation expects that the first letter text is a direct child of the
  11     ::first-letter pseudo object. The paged overflow / multicol implementation would violate this
  12     assumption by inserting a flow thread object between the ::first-letter pseudo object and the
  13     actual text.</p>
  14 <p>PASS if no crash or assertion failure.</p>
