Download is disallowed in Chrome

[KuznetsovVN]

Description of the problem

I'm trying to download a file from codesandbox page but it didn't.
There is a warning message in the console window: "Download is disallowed. The frame initiating or instantiating the download is sandboxed, but the flag ‘allow-downloads’ is not set. See https://www.chromestatus.com/feature/5706745674465280 for more details."

To Reproduce

Open this example
https://codesandbox.io/s/react-filesaver-example-wc1k9

Windows, Chrome - Version 91.0.4472.114 (Official Build) (64-bit)

Closing since this should be discussed/worked on in the issue.
