Bug: custom error_page doesn't work for HTTP 413 (content too large)

[estebistec]

I just discovered that there was more to our stack than I originally
knew. So we have nginx instances layered and I didn't realize I was
hitting another before getting to the one I had configured. Let me
verify this but otherwise assume there's no problem. I'll report back if
the problem still exists, but I'm thinking not. Sorry for imposing my
confusions here.
