            Bug ID: 177487
           Summary: cssFloat missing in CSSPropertyDeclaration.prototype
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: rbyers at chromium.org

'cssFloat' in CSSStyleDeclaration.prototype is true in all engines except WebKit (tested WebKit nightly at r222497)

Specified here: https://drafts.csswg.org/cssom/#the-cssstyledeclaration-interface

The property exists in WebKit, it's just completely hidden from enumeration:

'cssFloat' in document.body.style
> true
Object.getOwnPropertyNames(document.body.style).indexOf('cssFloat')
> -1
Object.getOwnPropertyNames(Object.getPrototypeOf(document.body.style)).indexOf('cssFloat')
> -1
