Closing "Agents Window" kills local devcontainer

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The version of Cursor IDE is largely irrelevant for this current issue. If you have Cursor IDE open, connected to a local devcontainer (macOS host, Linux[Ubuntu] devcontainer) and you then click on “Agents Window”, it now successfully opens a devcontainer [good, well done Cursor team]. However, if at any time later, I close this “Agents Window”, it kills ALL devcontainers (both Agents Window) and also my local one. That is bad.

Steps to Reproduce

  1. Open Cursor on macOS
  2. Open Linux/Ubuntu devcontainer
  3. click on “Agents Window”, loads up a devcontainer
  4. Close Agents Window. Wait <60 secs and your original devcontainer will now be disconnected from you, forcing a rebuild/reopen/re-connection

Expected Behavior

Cursor does not do bad things like disconnect my local devcontainer just because I closed the “Agents Window”

Hey all,

A fix is not slated for v3.11. No ETA to share at this time. We’ll keep you posted if that changes!
