Search for user doesn't work when executed from a post view

To reproduce, go to: https://blog.openhive.network/introduceyourself/@gtg/hello-world select a person icon in the search box, then enter gandalf in the "Search users..." field
it will try to redirect to https://blog.openhive.network/[param]/[p2]/@gandalf
