    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to redirecting to index.html
        try_files $uri $uri/ @root;
    }

    # If nginx can't find a file, fallback to the homepage.
    location @root {
        rewrite .* / redirect;
    }

The fallback is not actually redirecting to index.html. This is actually sending a 302 to the root.
I have not tested this yet, but I think we need to say

try_files $uri $uri/ /index.html;
