resolves #95 (context: nitrojs/nitro#2310)
The issue is original implementation considered there is one placeholder candidate on each level of tree (cached into
placeholderChildNode
). If there is more than one, we need to find the right candidate.This PR fixes issue by assigning max depth to nodes when inserting and consider it when choosing the right candidate (it should have same remaining length of incoming request path)
(honestly this implementation is hacky, but for v1 we have no choice until fully rewrite in v2)
