swagger is crap about anchor links

[codefromthecrypt]

I wonder if upgrading would help? It is strange to me that we cannot link to a specific part of the swagger by clicking on the heading. We frequently need to refer to sections of the doc and currently anchoring to a line in the source is easier.

Ex. clicking on span I'd expect this to change the window location url
