After the LoadImageOutput node in a workflow uploads an image, if you switch to another workflow and then switch back to this workflow, the image in the LoadImageOutput node will be automatically updated.It should not update automatically as expected.

Reproduce the behavior described for a workflow containing a LoadImageOutput node: upload an image, switch to another workflow, then return. Trace which workflow or node state changes during the switch, and consider the issue done when returning to the original workflow no longer automatically updates the uploaded image.
