[Issue] Text does not fold.
[Issue]
  Text does not fold, again.

[Cause]
  The text contains a line break but DefineEditText's 'multiline' is 0.
  FP and Reel take account of line breaks and fold text even when the 'multiline' is 0.
  (Actually, FP displays only the first line, while Reel displays the second line.)

[Fix]
  Follow Reel's behavior.
