Suppose the alias for '/node/123' is '/article/foo'.
Calling \Drupal::service('path.alias_manager')->getPathByAlias('/article/foo') returns '/node/123'. This is a useful Drupal core function at times.
However, \Drupal::service('path.alias_manager')->getPathByAlias('/article/foo/edit') returns '/article/foo/edit', while I would have hoped/expected to get '/node/123/edit'.
Is it possible for the module to support this?

It's likely this issue predates Contrib.social: some issue and comment data are missing.
I don't think this would be very feasible. The module doesn't create aliases for all the paths, it uses path processing to make it as if those are the real paths. I'd love to be proven wrong because I can see cases that would be not ideal, but I think that is a limitation of this implementation.
