Description

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have custom nodes enabled

### What happened?

The rgthree Power Loader node no longer renders correctly when using ComfyUI_frontend@latest.
The node appears as an empty/blank area and all controls/model selectors are missing.
When I switch back to the normal/default frontend, the same Power Loader works correctly.
I have attached screenshots showing both the broken latest frontend and the working normal frontend.

Research direction

Start by reproducing the issue with ComfyUI_frontend v1.53.3, Chrome/Chromium, and the rgthree Power Loader node, then compare its rendering with the normal/default frontend. The work is done when the Power Loader displays its controls and model selectors correctly under ComfyUI_frontend@latest.
