Promise never resolves when dialog is canceled

If the user clicks "Cancel" in the file dialog that is shown, the promise never resolves. If code is written using async/await, this means that the function that is awaiting the promise is leaked (it will always be waiting forever).
There are some suggestions how to address this here: https://stackoverflow.com/questions/34855400/cancel-event-on-input-type-file

@dlech Thanks for the report.
I will investigate the solution.

Later, I found that a "cancel" event has been added to <input type="file"> elements in the HTML spec: whatwg/html#6735
I'm not sure that any browser has implemented this yet though.
