Render "li" returns html instead of json

[xlegs]

I want Hugo to generate a JSON API alongside my pages. I am using the output formats feature, and the following layout templates in layouts/_default/

baseof.json.json

{
    "data": {{ block "main" . }}{{ end }} 
}

single.json.json

{{ define "main" }}

{{ .Render "li" }}

{{end}}

li.json.json

{
    "name": "{{ .Title }}",
    "location" : "{{ .Params.Location }}",
    "website" : "{{ .Params.Website }}",
    "logo" : "{{ .Params.Logo }}"
}

list.json.json

{{ define "main" }}

{{ range $index, $e := .Data.Pages }}
    {{ if $index }}, {{ end }}
    {{ .Render "li" }}
{{ end }}

{{end}}

Rendering the html works fine. It only fails when outputing a list of json objects.

Output for single

{
    "data": 

{
    "name": "A",
    "location" : "A",
    "website" : "A",
    "logo" : "/img/uploaded/logo.png"
}

}

Output for list

{
    "data": 
    
    <a href="/universities/a/" class="no-underline pa3 bg-grey-1 br1 mb2 db raise w-100">
	<h2 class="f3 b lh-title mb1 primary">A</h2>
	<p class="mid-gray lh-title mb2">Mon, Jan 1, 0001</p>
	<p class="mb0"></p>
	<p class="link b dib black mb0">Read more →</p>
</a>

    , 
    <a href="/universities/b/" class="no-underline pa3 bg-grey-1 br1 mb2 db raise w-100">
	<h2 class="f3 b lh-title mb1 primary">A</h2>
	<p class="mid-gray lh-title mb2">Mon, Jan 1, 0001</p>
	<p class="mb0"></p>
	<p class="link b dib black mb0">Read more →</p>
</a>

}

For whatever reason, the output for list renders the li.html template, but the json template is correctly rendered when rendering a single. This is inconsistent behavior.

Can anyone look into this?
Thanks
