text-decoration on parent box in a vertical writing-mode with children affected by varying vertical-align values does not keep constant position
DHTML test ---------- http://www.gtalbot.org/BrowserBugsSection/CSS3TextDecoration/text-decoration-position-sample-dhtml.html Such test is a simple text variation of the "ABCD" example from figure 6 in https://drafts.csswg.org/css-text-decor-3/#text-underline-position-property Expected results ---------------- There should be one and only one vertical straight, unbroken line under the baseline of the whole word "sample" in all 5 writing-modes. Explanations ------------ The position of text decoration lines applying to a parent box must be determined in relation to the same baseline and is not affected by 'vertical-align' applied on its descendants. Notes ----- - This spun from bug 1220438 comment 30 - No browser currently passes this test - I am using Firefox 48.0a1 buildID=20160406030221 and it fails the 4 vertical writing-modes - I use Linux 3.16.0-85-generic x86_64, Qt: 4.8.6, KDE 4.14.3; Kubuntu (trusty) 14.04.4 LTS - I've searched for duplicates and did not find any.
