Looks good to me.

Supporting this will be help authors create documents where they no longer have 
to choose between using semantically correct markup (small kana) and making 
ruby look like what they want (full-size-kana).

More tests are good, but I've already submitted a PR for this. I suggest 
reviewing it while you're at it.

Pay no attention to "at risk", this is merely about allowing us to push this 
feature from one level of the spec to the next if we try to transition level 3 
out of CR before this is implemented in all engines. This doesn't mean we're 
not confident in the design of the feature.

Intent to implement and ship: text-transform: full-size-kana

2018-10-13 Thread Xidorn Quan
Summary: A new value of text-transform to convert small Kanas to their 
full-size counterparts to increase legibility in the expense of accuracy, 
usually when font size is small, e.g. in ruby.

Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1498148

Link to standard: 
https://drafts.csswg.org/css-text-3/#valdef-text-transform-full-size-kana

Platform coverage: All platforms

Estimated or target release: 64

Preference behind which this will be implemented: N/A

Is this feature enabled by default in sandboxed iframes? Yes.

DevTools bug: no extra devtools support is needed.

Do other browser engines implement this? No signal.

web-platform-tests: A new wpt is being added in the implementing bug.

Is this feature restricted to secure contexts? No, because it is just a new 
value to an existing CSS property.


This feature is currently marked "At Risk" in the spec, but it is a small 
feature, and causes mostly just cosmetic changes, so it is unlikely to cause 
any webcompat issue for shipping or unshipping if needed.

There's another crux worth mentioning. Tests can be definitely passing or
definitely failing, but then there are various crash/error/timeout/etc
results where the validity of the test is uncertain, or it's quite likely
to be a flake or infra issue. In my report I've been conservative and used
1 PASS + 3 FAIL as the criteria. Fiddling with these rules can reveal lots
more potential issues, and if you like I could provide reports on that too.

Right, since there's no way to link to a subtest, in those cases I've
linked to the test and it might take some work to spot which subtest it
was. If this is a problem I could improve the report.

Thanks for filing the tracking bug, l hope there's some failures in here
that point to problems that really affect web developers that can be fixed.
