I confirmed this bug on Web Inspector of WebKit r120035, Windows 7 Home Premium SP1 64bit.
This bug still exists on WebKit r122832.
Please confirm, Web Inspector Developers!
By the time event is queried for properties, it already has no current target. Working as intended.
Oh, I'm sorry. I had misunderstood the Web Inspector's behavior. I will try to check the currentTarget property in a different way. Thank you.
