Issue descriptionUserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36 Steps to reproduce the problem: 1. Go to a website that doesn't fit in the browser view, like http://slashdot.org 2. Left click and hold the main browser window scrollbar marker as if to scroll up/down (do not release left mouse button!) 3. Right click (a full down/up click) in the browser window, you should see a context menu pop up 4. Release left mouse button The bug is now observable. Notice that the browser scrollbar is still active (black not grey) and move the mouse above and below the scrollbar marker. Notice that the scrollbar marker jumps to the mouse and the website scrolls -- it is stuck in the scroll state when it should not be. The bug remains active and you can interact with the website with left/right clicks, but if you mouse-over the right side it will annoyingly jump the website when you don't expect or want it. The way to deactivate the scrollbar is to left-click it again. What is the expected behavior? Right clicking the main window while you are scrolling should leave the scrollbar in a deactivated state What went wrong? Scrollbar remains active when mouse buttons are not pressed and moving the mouse over the right side of the browser scrolls the website Did this work before? N/A Chrome version: 61.0.3163.100 Channel: stable OS Version: 4.13.3-1-ARCH Flash Version: If this is a feature I request you remove it. Thanks!

You almost had it. You have to right click in the main window while holding the scroll marker instead of clicking on the scoll marker itself. Left click scroll marker hold, right click main window, release all mouse buttons -> bug activated

Here's a video. The video is a bit frantic maybe, and I use the scroll wheel, but pay attention to when the scroll marker is grey (inactive) vs when it's black (active). I demonstrate the bug twice. Clicking the scroll marker deactivates the bug state. Play the clip with vlc. I couldn't try on the new Chromium btw. Sorry! Cheers!

doug.coleman@ - Thanks for clarification...!! Able to reproduce this issue on Win-10 and Ubuntu 14.04 using chrome reported version #61.0.3163.100 and latest canary #63.0.3236.0. Issue is not seen on OS-Mac. This is a non-regression issue as it is observed from M50 old builds. Hence, marking it as untriaged to get more inputs from dev team. Thanks...!!

No problem! Actually, I misspoke above -- you can trigger the bug by left-clicking and then right-clicking solely the scroll marker. Your video even did this but you didn't click around enough to notice the effects.
