So, after a little digging on Stackoverflow I decided to try an explicit
lookahead. For what ever reason it works.

/\s(".*?")(?=\s|$)/ matches where /\s(".*?")(\s|$)/ won't.
It sounds like you have a solution, but don't understand it. I'd like to help you understand it, but I don't understand what you're trying to match. The sample string you provide above does not match your regex (and obviously so, as there is never whitespace before a quote)

Could you please provide a single string that you're matching against, and describe what you are trying to match?-Boundary_(ID_6zU3/wC6ZvY5pbY2Y/cdiA)
