Enable CSSOMViewScrollingAPI
https://bugs.webkit.org/show_bug.cgi?id=189472
Patch by Frederic Wang <[email protected]> on 2019-01-22
Reviewed by Simon Fraser.
This patch enables the CSSOMViewScrollingAPI option by default. This feature has already been
enabled in tests since r235855. Basically, this change fixes an old compatibility issue
regarding which scrolling element correspond to the viewport in standard mode (WebKit uses
document.body while Gecko/Edge/Chromium use document.documentElement as described in the
CSSOM View specification). WebKit developers writing tests can use document.scrollingElement
for that purpose, so that they work independently of whether the option is enabled.

* Shared/WebPreferences.yaml: Enable by default and remove "experimental" category in
accordance with the new policy. Instead, keep an internal flag only for developers.
