<title>CSS Pseudo-Elements Test: paired cascade: UA default highlight colors are used when highlight pseudo has declared color value of revert</title>

<meta name="assert" value="This test verifies that setting color to revert on ::selection does not suppress any UA non-initial used value for background-color. Because the revert value rolls back the cascade, it destroys its own existence as a cascaded value, and this is also true under paired cascade.">
