<title>CSS Pseudo-Elements Test: paired cascade: rule includes highlight pseudos other than ::selection</title>

<meta name="assert" value="This test verifies that setting color on ::target-text suppresses any UA non-initial used value for background-color. ::target-text is a highlight pseudo with a recommended UA default background-color that is not initial (Mark), so paired cascade can be observed.">
