Bug in content negotiation when specifying a default format and including it in a call to respond_to() helper about mojo

[kraih]

I don't quite see the bug i'm afraid, the logic seems to follow the documentation in the precedence order it is described. https://docs.mojolicious.org/Mojolicious/Guides/Rendering#Content-negotiation

From the documentation you pointed, I imagine you're referring to this phrase as the precedence order:

The best possible representation will be automatically selected from the _format GET/POST parameter, 
format stash value or Accept request header and stored in the format stash value.

If so, ok, it looks like the correct behavior.

But then, what would be the correct way to change a single endpoint to a fallback response format using content negotiation? (it seems to me that Accept: */* header doesn't match the any format).
