Hi,

We have found a strange issue that I have created a REPL to reproduce: https://blazorrepl.telerik.com/cnupFJbS23F6HHJ006

1. Select a .doc file

2. Select a second file

3. Click the "Copy Memory Stream" Button

the method stops at CopyToAsync for the .doc file

It seems to work fine if the files are selected together or if different file types are used

I have been testing with the attached .doc and a blank .txt file
