Dev channel update to 79.0.308.1 is live

Noticing the screenshots that rw1234 included regarding inconsistent scrolling, this reminded me that I often wonder why the arrows above and below scroll bars are now so minute. Many of my older clients like to place their pointer over the arrows to click them to gradually move content up and down, rather than clicking and holding the scroll bar 'handle' or using gestures on their touchpad with fingers, which if you are over the age of 80 can be quite challenging! The arrows are really difficult to see sometimes.
