User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:32.0) Gecko/20100101 Firefox/32.0 (Beta/Release) Build ID: 20140602072051 Steps to reproduce: On Safari beta for Yosemite, it breaks underlines for descenders. Firefox should also do that.

I'm tempted to dup this on bug 812990 as it will implement text-decoration-skip: ink; it actually looks like safari breaks the specifications here as the initial value is meant to be "objects" not "objects ink".

The initial value for new properties is chosen largely due to compat concerns. If it's better and doesn't break a lot of sites to have a different initial value, we could ask the CSSWG to change the initial value.

According to CSS2.x, section E.2 Painting order https://www.w3.org/TR/CSS21/zindex.html#painting-order and https://www.w3.org/TR/CSS22/zindex.html#painting-order (look for 4. For inline elements: 1. 1. 1. any underlining affecting the text of the element (...) and 3. the text. ) underlining painting is done before glyphs are painted; therefore, if the underlining crosses the descenders (glyphs like 'g', 'j', 'p', 'q', 'y' have a descender), then the descender part must overlap the underline. This is also re-confirmed by CSS3 Text-decoration: https://www.w3.org/TR/css-text-decor-3/#underline-auto The descender of black "p" overlaps the blue underline in figure 3. We have a test (you must install Ahem font for this test: AHEM____.TTF from https://www.w3.org/Style/CSS/Test/Fonts/Ahem/ ) on this: http://test.csswg.org/suites/css2.1/nightly-unstable/html4/painting-order-underline-001.htm Firefox 52+ and Chrome 60+ pass this test. attachment 8433172 [details] would be good, correct for a 'text-decoration-skip: ink' test.

Sounds likes Chrome has just implemented this. Any chance we can get it triaged and maybe confirmed and assigned?

Status: "UNCONFIRMED" seems to be wrong.

Duping forward to bug 1411922, which covers the text-decoration-skip-ink property (now that it has been split out from text-decoration-skip).
