Revision e8c4654cef692388e68e8ded7a9316d6bd613570 authored by Darren Shen on 06 April 2018, 07:51:02 UTC, committed by Chromium WPT Sync on 06 April 2018, 07:51:02 UTC
We cannot support background-repeat and background-position yet because
they are both implemented as shorthands in Blink, but are not shorthands
in the spec.
We'd need to refactor the existing code to allow shorthands to reify
as proper Typed OM objects. There are also some tricky bits to support
styleMap.set with shorthands given a proper Typed OM object.

<h1>Description</h1>
<p>This test validates that the page properly becomes hidden and visible due to switching tabs.</p>
<h1>Manual Test Steps:</h1>
<p>
<ol>
<li> Ensure this page is the foreground and click the "Start Test"</li>
<li> Switch to another tab</li>
<li> Return to the current tab containing this test page</li>
</ol>
Note: This test will automatically timeout and fail if not completed within 60 seconds.
