OK, this sounds bad. But... Devil's advocacy here: are there any real-world examples of actual sites whose event behavior was actually broken by this change in Chrome 56? It happened a few months back, and I don't remember anyone complaining. I mean... it broke the author's app. Probably a few others somewhere. But it seems not to have broken anything significant. I guess I fail to see the concern here. It's an edge…
I actually had no idea what could've broke it until I saw this submission. It's still not going to be fixed though since I don't remember the code. I assume a lot of people are in a similar position.
