Docker update cleared my .hosts file

[TobseF]

Description

After I updated my Docker Desktop with winget to the version 4.33.1, the setup cleared my .hosts file under:
C:\Windows\System32\drivers\etc\hosts

I had several rules defined there. But after the setup, there was only the docker section left:

# Added by Docker Desktop
192.168.142.42 host.docker.internal
192.168.142.42 gateway.docker.internal
# To allow the same kube context to work on the host and the container:
127.0.0.1 kubernetes.docker.internal
# End of section

I recognized this, because my firewall warned me that my .hosts file was changed.

Reproduce

1. Install Docker Desktop
2. Put something in your .hosts file

   127.0.0.1       localhost
    ::1             localhost
    192.168.0.1       my.router
   

3. Install a Docker Desktop update
4. Check your host .hosts and search for your entries.
   They are gone now, and only the # Added by Docker Desktop block is left.

Expected behavior

Docker should never overwrite the .hosts file. Especially without a warning.
I should only append its block on top or bottom of the file. If it needs an update to its configuration, it should try to clean up only the old docker configuration lines and never user-defined lines.
