Problem

trailing slash in link for legit page works for client side navigation but leads to not found bundle and 404 on hard refresh (ssr) Bug report Describe the bug let me know if title needs further clarification. all relevant issues has been closed with reasoning that its been fixed in 6-canary (I believe it is not) or by improved serve (which is true only in perhaps production static export).
