Making clickable links and viewable images in editor

I’d like to continue using relative markdown link and image syntax in my editor, which allows me to navigate to linked content and view local images as I write.

[link to post2](./post2)

In Hugo, I made use of their markdown render hooks to achieve this:

{{ $link := .Destination }}
{{ $isRemote := strings.HasPrefix $link "http" }}
{{- if not $isRemote -}}
{{ $url := urls.Parse .Destination }}
{{- if $url.Path -}}
{{ $fragment := "" }}
{{- with $url.Fragment }}{{ $fragment = printf "#%s" . }}{{ end -}}
{{- with .Page.GetPage $url.Path }}{{ $link = printf "%s%s" .RelPermalink $fragment }}{{ end }}{{ end -}}
{{- end -}}
<a href="{{ $link | safeURL }}"{{ with .Title}} title="{{ . }}"{{ end }}{{ if $isRemote }} target="_blank"{{ end }}>{{ .Text | safeHTML }}</a>

…but I’m not sure how to do the same in Zola.

I’ve thought about using filters/replace but haven’t been able to figure it yet.
I suppose I could get my own fork and roll back to the earlier use of “./” for internal links, but I was hoping there’d be a cleaner way.

I know this question was brought up earlier in 2020, but not sure if anyone’s found a solution that works for them yet.
