hosts file is not updated when restarting docker desktop after changing network interface. #14076

Description

Hi I work hybrid. at home I work wireless and at the office LAN. My docker desktop is configured to use WSL 2 based engine and I have the "Add the .docker.internal names to the hosts..." checked. When I switch from work to home and visa versa , I use a different network interface with a different local ip. I would expect docker desktop to update the hosts file with the local ip each time I restart docker desktop, but it doesn't. My hosts file remains with the previous mapping. The only way I manage to update the hosts file is to uncheck .docker.internal...." and then check again. Why doesnt it update the hosts file automatically each time the docker desktop restarts ? Thanks.

Reproduce

simply change the network adapter , and restart docker desktop. it doesn't update the hosts file.

Expected behavior

I would expect the hosts file to be updated with the default local ip of the current network interface , each time docker desktop is restarted.
