【Load video node】The video types supported by the ‘Load video’ node are incomplete.

### 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?

The Load video node can actually upload .mov files (and perhaps some other file types). However, when you click the 'upload button', in the popped - up folder, the files will be automatically filtered to only show .mp4, .m4a, and .webm files.

### Steps to Reproduce

Files will be automatically filtered to include all the file types supported by the Load Video Node, and the front - end can display them correctly, such as videos with transparent backgrounds.
