Permalink for Translation Homepage wrong with uglyUrls

[Lednerb]

With uglyUrls turned on:
uglyUrls = true

And given the following code block:

{{ range $.Site.Home.AllTranslations }}
    {{ if eq ($.Scratch.Get "language") .Language }}
        <a href="{{ .Permalink }}" class="active">{{ .Language }}</a>
    {{ else }}
        <a href="{{ .Permalink }}">{{ .Language }}</a>
    {{ end }}
{{ end }}

I would expect to get the following .Permalink output:
/de/index.html

Instead I get:
/de/

Affected hugo version
Hugo Static Site Generator v0.64.0-241DB8F7 linux/amd64 BuildDate: 2020-02-04T09:10:23Z

Is this a bug or do I miss something?
