Atto inserts a line break every 255 characters

The Atto editor inserts a line break in the text approximately every 255 characters when the text is delimited by <br>, <p> or <div> tags. Note that it does not do this when the text is delimited by <span> tags.

In general, this does not adversely affect quiz questions. There is, however, cases where this behavior causes a problem.

For example, when the line break generated by the Atto editor cuts a short answer sub-question of a Cloze question, the sub-question no longer works correctly. Examples are given here that illustrate clearly this problem.
