pythongosssss dabfc6521e test: Add test to prevent regression of workflow corruption during graph loading (#10623)
## Summary

Adds regression test for
https://github.com/Comfy-Org/ComfyUI_frontend/pull/9531

## Changes

- **What**:  
- registers extension that triggers checkState during
afterConfigureGraph (at this point the workflow data and active graph
are not in sync), previously causing it to overwrite the workflow data
- switches between tabs
- ensures they are not corrupted

Line 35 can be uncommented to cause the test to fail by clearing the
isLoadingGraph flag
