I've been using this site today to test out various examples while
modifying the Regex Builder plugin and I think I have come across a bug in
LC.

The following regex works in the web site.  It's also one of the examples
in the RegExhibit program and, naturally, works there too.

[the]{3}\s(\w+)\s.*?(?=;)

The regex matches the first occurrence of the word "the" followed by a
space followed by any number of words/spaces until a semicolon is found.

Using matchText in LC 6.5.2 it fails with error 301 pattern error.

If I remove "(?=;)", the error goes away but the match matches "the" and
just the next word.

Before I go to the QCC, any regex experts out there who can think why LC
would flag an error on this?
