Today we have two different modes for stylus input:
 1. Android: Direct manipulation / touch-like - stylus drag scrolls
 2. Everywhere else: Indirect manipulation: mouse-like - stylus drag selects text

We've debated which behave is better for ChromeOS (was there any public discussion of this I can link to?  From a quick search I find just internal threads / bugs).

Microsoft is exploring whether it could make sense for a pen to scroll by default in Edge, which means we might want to consider doing that on (at least) Windows as well.

How much work would it be to add a flag which switches Chrome on Windows (ideally also ChromeOS) to use the Android model where the pen scrolls?
