From Sale create a new (or edit) SO. Add a note to the order with a log
line without dash or whitespace (i.e. a url). Click on "Preview".

The sale portal will try to display the long line which will overflow
the standard size of the column creating an ugly overflow with a very
long horizontal scrollbar.

Adding a "break-all" rule to fix the sale portal case.
