Description
Description
When switching between runs in the history panel, the run visualization sometimes disappears from the diagram.
Steps to reproduce
- Open a workflow in the collaborative editor
- Select a run from the history panel
- Switch between runs with different statuses (e.g., success → crash → success)
- Observe: run visualization may disappear briefly or go missing
The behavior is flaky.

Research direction
Start by reviewing PR #4201 and tracing run selection in the history panel of the collaborative editor. Reproduce the success → crash → success sequence and inspect how the run visualization is updated between selections. Done means the visualization remains present and correct when switching among runs with different statuses, with regression coverage for the flaky case.
