Additional Notes
This edge case was where we trim the trailing slashes on the rewrite-target before appending the contents of the matched path. This behavior was required becuase it ensures that we don't duplicate slashes.
However, it introduced an edge case where if the trailing slash was the leading slash, it could get lost.
This is that edge case. The solution here is to capture the leading slash as part of the path capture group, and append it to the rewrite target.
