<meta name="assert" content="This test verifies that non-applicable property declarations are ignored in highlight pseudos, that the computed values of ‘font-size’ and ‘line-height’ in highlight pseudos are taken from the originating element, and that ‘text-shadow’ in highlight pseudos respects these values when given ‘em’ and ‘lh’ units.">
