Reftests

Test	Result	Variants	Kind	Description
`webkit-background-origin-text.html`	Pass	1 / 1
`webkit-box-align-001.html`	Pass	1 / 1
`webkit-box-blockify.html`	Pass	1 / 1
`webkit-box-clamp-bottom-border.html`	Pass	1 / 1

`webkit-box-horizontal-rtl-variants.html`	Pass	1 / 1
`webkit-box-ignores-flex-wrap.tentative.html`	Pass	1 / 1
`webkit-box-rtl-flex.html`	Fail	0 / 1	BUG	the antialiased glyphs of the test and of the reference differ on their edges: they are not painted the same way (another color, a group, a shadow or a compression; on macOS the coverage of the glyphs depends on the luminance of their color; not analyzed individually)
`webkit-box-z-index-002.html`	Pass	1 / 1
`webkit-box-z-index.html`	Pass	1 / 1
`webkit-input-placeholder.html`	Fail	0 / 1	NOT IMPLEMENTED	the legacy `::-webkit-input-placeholder` alias of `::placeholder` (https://github.com/whatwg/compat/issues/65): the selector parses, like every `-webkit-` pseudo-element, but matches nothing
