Improves accessibility by making scroll containers focusable using sequential focus navigation by changing their default tabIndex value from -1 to 0. Today, the tab key doesn't focus scrollers unless tabIndex is explicitly set to 0 or more. By giving scrollers a default tabIndex of 0, users who can't (or don't want to) use a mouse will be able to focus clipped content using a keyboard's tab and arrow keys.
