[Bug]: Can't change node shape ( since v1.38.9 )

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have searched existing issues to make sure this isn't a duplicate
- [x] I have tested with all custom nodes disabled ([see how](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled))

### What happened?

Since frontend 1.38.9 I can no longer change the node shapes via right click, shapes menu. I can select e.g.. 'box', but the node shape stays default i.e.. round.

### Steps to Reproduce

2. Select right click - shapes. Select 'box'
3. Node shape remains unchanged
