Steps to reproduce the problem:
1. click on a link that have a download attribute
2. onbeforeunload function is called

What is the expected behavior?
With Chrome 64 onbeforeunload was not called

What went wrong?
If I don't set the target attribute, the defaut one is supposed to be "_self: Opens the linked document in the same frame as it was clicked (this is default)
So there is no reason to call onbeforeunload function

If I set the target to "_blank": Opens the linked document in a new window or tab; the onbeforeunload is not called

Did this work before? Yes Chrome 64

Does this work in other browsers? N/A
