Doesn't work in public shared folder

The .HEADER.md and .README.md files doesn't show up in public shared folders. If I share them with other users or groups, there they can see the content.

How it look for me and for other users:

How it loock for public folders:

I am using Nextcloud 18.0.3 and yes, I know there is no offical support. But the build-in "rich workspace" is works poorly. I disabled it and while reading other issues here you tasked about NC18. So I hope you will continue developing this app also for NC18. It is wonderful app that I never want to miss. You even can use hidden files, really nice!

However, If you need something else, just tell me.
