Re: [csswg-drafts] [css-scrollbars-1] Add `scrollbar-style` property for `overlay` scrollbars (#13218)

Thank you for the very detailed write-up.

My main concern would be that this makes it too easy for authors to override the preference of users. When users have deliberately set their system-settings to non-overlay scrollbars, having the author replace those with overlay scrollbars can be frustrating. The proposal here says:

> 1. **System Preferences**: Should `scrollbar-style: overlay` respect Windows "Always show scrollbars" setting?
>    - Suggested answer: Yes, system accessibility preferences should override author styles

However, I am not sure how we can tell apart a system+browser's default setting to show non-overlay scrollbars, which the user may very well like, from a user who has changed their settings to show non-overlay scrollbars.

For instance, I use Firefox on macOS, and I've changed my settings to use non-overlay scrollbars. The answer above suggests I'd get to keep those even if the author had set `scrollbar-style: overlay`, because system accessibility preferences should override author styles. However, when I use chrome on windows, `scrollbar-style: overlay` would win over the default of non-overlay scrollbars, even though I have the same preferences.
