[bug]: Opening a second remote workspace in VS Code closes the first window (only one at a time)

[dgarros]

Bug Description

When working with multiple remote workspaces connected over SSH, only one VS Code window can be open at a time. If I already have a VS Code window open for workspace1 and then open VS Code for workspace2, the existing workspace1 window is closed (replaced) instead of a second window opening alongside it.

I'd expect each remote workspace to open in its own independent VS Code window so I can work across several at once.

Steps to Reproduce

1. Configure two remote workspaces connected over SSH (e.g. workspace1 and workspace2).
2. Open workspace1 in VS Code from emdash — a VS Code window opens.
3. With that window still open, open workspace2 in VS Code from emdash.
4. Observe: the workspace1 window closes and is replaced by the workspace2 window.

Actual vs Expected Behavior

Actual: Opening a second remote workspace in VS Code closes/reuses the existing window, so only one remote workspace window can be open at a time.

Expected: Each remote workspace opens in its own VS Code window, allowing multiple remote workspaces to be open simultaneously (as VS Code normally supports with code -n / separate windows).

emdash Version

1.1.39

Operating System

macOS 26.5.2 (build 25F84) — client; remote Linux dev servers over SSH (Tailscale SSH)

Additional Context

• Both workspaces are on remote hosts reached over SSH (Tailscale SSH).
• This may be related to how emdash invokes VS Code / the Remote-SSH window reuse behavior rather than opening a new window per workspace.

Thanks for raising this, @dgarros - we weren't aware of this. we'll reproduce and get back to you here timely.
