  Log Message:
  -----------
  Implement scrollbar-width CSS property in WebKit Legacy
https://bugs.webkit.org/show_bug.cgi?id=257056

Reviewed by Tim Nguyen.

This change implements the missing code for the scrollbar-width CSS property none value to work inside of WebKit Legacy.

The thin value doesn't always have an effect in WebKit Legacy but this is spec compliant.
