API Explorer Model Schema Data Type 'Click to set as parameter value' misses to put wrapping structure?

If you try to use it (apidoc, Swagger) to e.g. PUT /config/toaster:toaster/ then a dumb end-user like me will naturally find and use that nice "example" parameter support that UI has - on e.g. the (config)toaster parameter, one can click on Model Schema under Data Type where it says e.g.

{ "darknessFactor": "integer" }

& 'Click to set as parameter value'.

Doing that will fill in

{ "darknessFactor": "integer" }

, make that

{ "darknessFactor": "500" }

and click that "Try it out!" button and: "Error parsing input: Schema node with name darknessFactor wasn't found..." - because it would actually have to be: {"toaster": {"darknessFactor": 500}}, only then it works.
