            Bug ID: 278193
           Summary: Page::updateRendering use of forEachRenderableDocument
                    should exclude hidden docs
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned at lists.webkit.org

Spec: https://html.spec.whatwg.org/multipage/webappapis.html#event-loop-processing-model:window-event-loop-3

Documents with a visibility state of "hidden" should be removed from the set.

We instead track visibility changes in Page::setIsVisibleInternal, and pause animations etc.
