Test results for hyphen wrapping in loose line-breaking are incorrect

[r12a]

https://wpt.fyi/results/css/css-text/line-break/line-break-loose-hyphens-001.html?label=experimental&label=master&aligned shows all browsers failing the test at https://github.com/web-platform-tests/wpt/blob/e3eb24eb27/css/css-text/line-break/line-break-loose-hyphens-001.html

however, that test passes if you actually look at the result of the test, see http://wpt.live/css/css-text/line-break/line-break-loose-hyphens-001.html

that the test passes is also supported by the i18n-test suite equivalent of that test. See https://www.w3.org/International/i18n-tests/run?base=css-text/line-break-property&batch=line-breaks-jazh&test=ja/css-text-line-break-ja-hyphens-loose.html

@frivoal i believe these tests are yours.

cc @himorin, since this affects a jlreq gap you recently submitted.

I just tested it. The results were different under different browsers:

---

Chrome 94:

---

Firefox 92.0.1:

---

Safari 15.0:

I suspect that we need to change lang to ja.

I also confirm test and reference shows the same output on Firefox 92.0.1 Windows, w/o changing language parameter (lang=en is coded in both html files).

@xfq you got different results for different browsers for the WPT tests (i suspect that this may be because the default language for ideographic content varies across browsers).

But did you also check the i18n test suite tests. I checked those for Japanese and found that Firefox, Chrome, and Safari all pass the loose hyphens test. https://www.w3.org/International/i18n-tests/results/line-breaks-jazh#ja_loose
