Bug: A session shows title and worktree name but no run/open/open canvas icon are shown

Bug:
Usually a session shows the title, worktree name, and on the right the run button and open button along with the open canvas icon.
I see a problematic session shows title and worktree name but no buttons for run, open, nor canvas icon.

Reproduce the missing controls on the /chat path using app version 1.0.21 on Windows 10, comparing the problematic session with a normal session. Trace the session UI entry point to determine why the run, open, and canvas controls are absent. Done means the affected session displays all three controls consistently.
