Reproduction Link

Steps to reproduce
Remove all uploaded files

Add a new document
Click the upload button

The fileList in console is still the original value
This property of flist-list can only be used for initialization

What is Expected?
File-list can update the file list synchronously

What is actually happening?
File-list cannot be updated synchronously

Currently, the way I found to hack it is to listen to the change event and assign the fileList every time

onChange(f:File,fl:File[]){
this.fileList = fl;
}
