ValueChange event fires twice


I have the following code hooked up to a file upload component.  Since version 21.1 this event seems to fire twice for each file (for a multiple file upload).

So, where I am uploading say 3 files, the output window would display 6 file names.

  public async Task ValueChange(UploadChangeEventArgs args)


    //Only ever one file since 21.1

    foreach (var file in args.Files)

We have considered the reported issue "When uploading multiple files, the value change event causes file duplication" as a bug on our end. The fix for the issue will be included in our upcoming patch releases by mid-May 2023.
