On the official demo page, if you enter one or more correct entries into the textarea (that get matches) and then type a string that doesn't match, it clears the entire textarea, not just the last entry.

Steps to duplicate:

• Go to http://jquery.bassistance.de/autocomplete/demo/
• Place the cursor in the textarea
• Press A, Enter (selects Aberdeen)
• Press S, Enter (selects Sabina)
• Press X, X... no match so it clears the entire textarea.

Expected behavior:

• Should only clear the last entry
