Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
In the past few versions (starting a week or two ago), when agent/plan chat decides on its own to use subagents for investigations, the callouts stay in “New subagent Starting up” forever. Even after they have obviously returned results (and “Starting up” still has that pulsating text effect as well).
And with this, no way to click into them to view progress/results of subagent investigation, or even the topic of each one.
Steps to Reproduce
Do that will trigger an organic submodule investigation (I dont ask for it, Cursor just decides to do it).
Expected Behavior
Subagent modules update to show the title, allow me to click on them to open new tab with progress/results of investigation, and stop “pulsating” when done, show status, etc.
