This PR adds optimistic rendering at two places: - In the `runWorkflowVersion`, to create a workflow run entry as fast as possible in the cache and render it immediately in the side panel. - In the `ListenUpdatesEffect`, to be sure the cache is properly set; we also need to set the record in the record store that's used in the fields card. ## Before https://github.com/user-attachments/assets/8b360ea9-c292-4e05-82a0-d2f12176bb6f ## After https://github.com/user-attachments/assets/2d11023c-2ceb-4fa3-a951-187b9a0b5743 ### With a slowed-down network https://github.com/user-attachments/assets/7d2a592a-1ea7-455b-856f-bf3d9d905061 ## Follow up I will create next a PR to ensure the viewport is always set when we know the dimensions of the nodes.
