Original GitHub issue: https://github.com/Comfy-Org/desktop/issues/510

Frontend Versionv1.4.13

Expected BehaviorWorkflow where the seed widget of the Ksampler node has been converted to input and a primitive node is attached to input the seed.
The primitive node is set to "randomize" to generate a random seed each run.
Copying and pasting these nodes should retain the "randomize" state of the primitive node.

Actual BehaviorWhen pasted, the primitive node switches to "fixed"

Steps to ReproduceCopy and paste a workflow or part of a workflow (including the primitive and Ksampler nodes) where the seed widget of the Ksampler node has been converted to input and a primitive node is attached to input a randomized seed. The state of the primitive node will change from randomize to fixed.
