<title>CSS Pseudo-Elements Test: paired cascade: UA default highlight colors are not used when highlight pseudo has declared color value of unset</title>

<meta name="assert" value="This test verifies that setting color to unset on ::selection suppresses any UA non-initial used value for background-color. The unset value is defined as both “treated as [inherit or initial depending on whether the property is inherited]” and “effectively erases all declared values occurring earlier in the cascade [(inclusive)]”, which are normally equivalent, but under paired cascade, the former wins.">
