Closes #2286
The CI code scanning previously warned about our stack trace regexes having the potential for DoS due to backtracking and exponential time required for large input strings. We ignored these CI warnings since the JavaScript SDKs have always contained these regexes but since a customer has reported a 90 second hang caused by this it makes sense to add some sensible limits.
