Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
I’m trying to set up Dev Container on a remote machine connected through Remote - Tunnels. I got the error pop up in the GUI “Anysphere Remote Containers requires the Anysphere remote extensions. Please install the Anysphere Remote extensions and try again.”. When I tried “Dev Containers: Reopen in Container”, the same error showed up in Output - Dev Containers. It is unclear which “Anysphere Remote extensions” I should install and where I can find them.
Steps to Reproduce
Use Remote - Tunnels to connect to a remote machine and run “Dev Containers: Reopen in Container”.
Expected Behavior
Successfully reopen workspace in dev container.

Does this stop you from using Cursor
Yes - Cursor is unusable
