Hi,
There seems to be some discrepancy in behavior of apps using CEF (and on Google Chrome) on MAC 10.11 and above. Sometimes, when we change the value of preference "Show Scroll Bar" to "Always Allow", the scroll bar is shown only when we are scrolling wherein it should be shown always. And sometimes, even if we select "Show when scrolling" , we can always see scroll bar in chrome even if it not being used. This behavior is intermittent and can be seen on latest Chrome on MAC 10.11 and above whereas other browsers seems to be working fine. Pls. look into this.
Steps to reproduce
1. Open System Preferences
2. Go to General
3. Change "Show scroll bar" to "Always Allow"/"Show when scrolling"
