Can't scroll after stopping mouse over a horizontal scrollbar

Project Member Reported by esprehn@google.com, Jul 19 2017

Issue description

UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3160.0 Safari/537.36

Example URL:
https://g3doc.corp.google.com/company/teams/mac-road-warrior/index.md#screen-configuration-linux

Steps to reproduce the problem:
1. Scroll down until your mouse is over a horizontal scrollbar.
2. Pause scrolling.
3. Try Scrolling again.

What is the expected behavior?
Should continue to scroll.

What went wrong?
Trapped! It seems scroll latching prevents you from scrolling if you're over a horizontal (probably vertical too, but you don't scroll that direction often) scrollbar.

This is very annoying because if you're not scrolling quickly you can end up getting stuck and then you need to wiggle the mouse to get free.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? Yes 

Does this work in other browsers? Yes

Chrome version: 61.0.3160.0  Channel: n/a
OS Version: OS X 10.12.5

Note that I have "Always show scrollbars" turned on, if you have auto hiding ones I bet you don't notice this bug. It's very annoying though.

This worked fine in 59.0.3071.115, and is broken in 61.0.3160.0

Latching isn't yet enabled so it seems that this is an issue with how events get chained. Interestingly, it's specific to Mac - I can't repro on Linux. I bet it's a special case in scrollbar event handling somewhere.

Sorry, missed that this was a regression. Lets fix for M61.
