empty subagent ui #28171

Description

Sometimes the subagent's page is completely blank, but you can see the content after waiting patiently for the subagent to end.
Sometimes, when an immediate termination is initiated, no content can be seen from the outside, and clicking inside also shows a blank black screen.

Plugins

none

OpenCode version

Steps to reproduce

This issue occurs intermittently and appears during normal operations. I don't know how to reproduce it. However, I just discovered it today. Previously, even when I had the main agent launch 80 sub-agents at once, everything worked fine
