Bug 1515858 [wpt PR 14623] - [LayoutNG] Don't allow line height quirk…

… inside list items., a=testonly Automatic update from web-platform-tests [LayoutNG] Don't allow line height quirk inside list items. This makes us match legacy engine behavior more closely, and both Edge and Firefox have something similar, although Firefox triggers based on element type (LI), and not display type (list-item). There's currently nothing in the spec [1] that suggests such special behavior for list items. [1] https://quirks.spec.whatwg.org/#the-line-height-calculation-quirk This fix makes the line height differences go away in the test tables/mozilla/bugs/bug23235.html (but note that it will still require a rebaseline, because of minor text rendering differences between legacy and NG). See whatwg/quirks#38 for spec discussion.
