Issue #2932007 by googletorp, cedewey: Maxlength disables WYSIWYG fields when...

  // Sets the data into a ckeditor.

  ml.ckeditorSetData = function(e, data) {

    // WYSIWYG can convert '\r\n' to '\n' and insert '\n' after some tags, this

    // can result in circular changes as what is attempted to be inserted and

    // what is actually inserted is different. We save the last inserted value

    // on the editor to stop this issue.

    if (e.editor.mlLastBeforeInsert !== e.editor.getData()) {

      e.editor.mlLastBeforeInsert = e.editor.getData();

      // Calling setData() will place the cursor at the beginning, so we need to

      // implement a callback to place it at the end, which is where the text is

      // being truncated.

        e.editor.getSelection().selectRanges([range]);

      }});

    }

  }
