Hugo server redirect to wrong output while live-reloading page

I configured Hugo to outputs gemini files.
I added a mediaType, an outputFormat, it works very well.

Sadly when using hugo server --navigateToChanged while creating new content, my web browser always get redirected to the gemini output instead of the html output. I must manually edit the url to get the html.
Is there a way to ask Hugo to only redirect to html output ?

You can find my whole website repo if it can help.

Your repository is offline. There might be a confusion with the URLs for the changed markdown file.

Ho sorry. My repo is only available through IPv6.
here is a github mirror.

A little bump.

Any idea ?
