I do not get the full same results that you report, when I use 1.9.2.

No. Your "error_page" with "=" eats the 418 status.

I do get that much.

I only get 404 if error_page.html does not exist. If it does exist,
I get it with http 200.

Aside from that: I suspect that proxy_intercept_errors does exactly the
opposite of what you think it does.

What happens if you set it "off"?

error_page normally does not change the http status. Your extra config
told it to change it.
