Canary build scroll bar hasn't worked using mouse click/drag for the last few builds. Dev works fine. Can scroll with touch, mouse wheel, touchpad gesture and scroll bar buttons, but the bar itself doesn't respond to click.
@natelaff Do you enable "Enable compositor threaded scrollbar scrolling" in edge://flags/?
In my case, enable this feature will be the same situation as you.
@natelaff FWIW:Mine, in Canary, has & does work fine... without adding anything.Cheers,Drew
