I'm attempting to use podman desktop on Windows (instead of docker desktop), and would prefer to use rootless podman. Unfortunately, it won't start podman compose configurations of any sort if the devcontainer contains a feature. Single-container devcontainers work fine, but the process of building/launching a compose version breaks with a feature breaks.

Steps to Reproduce:

1. Install Podman Desktop, and set rootless mode with podman machine set --rootful=false (you may have to stop/restart the machine)
2. Attempt to create a devcontainer definition that uses a compose file. The default c# and Azure SQL one does this, but even a stripped-down one with only a single container reproduces the error. You can create a working container definition and then substitute these contents: .devcontainer.zip
