LPS-42815 - Error message style does not wrap around long word without spaces completely in entry preview

Hi Jon,

Attached is an update for https://issues.liferay.com/browse/LPS-42815.

I wasn't sure where the best place for this fix would be.  I originally thought at the portlet journal level, because that is the only place it is really needed.  But I decided to put it at the theme level because that is where we have the alert style for word-wrap.

Please let me know if there are any issues.

Thanks!
