Error when remove a file that is in receiving

[edwardwohaijun]

At first, I though that's because the file is being written and removed at the same time. The error message is clear enough:
Uncaught (in promise) DOMException: It was determined that certain files are unsafe for access within a web application, or that too many calls are being made on file resources.
But even I move the "fs(fileObj).then(getFile).then(removeFile) call" in _updateProgress(), which is a callback passed to onwriteend. The error still occurred.
