accept the overflow-wrap property
"For legacy reasons, UAs must treat ‘word-wrap’ as an alternate name for the ‘overflow-wrap’ property, as if it were a shorthand of ‘overflow-wrap’." http://dev.w3.org/csswg/css-text/#overflow-wrap
This is a Gecko bug wrt spec compliance. As this is part of CSS3-Text (and not a new spec), I reset the severity to normal. IMHO, only if this concerned a new spec that has no prior implementation in Gecko, the "enhancement" value would be justified.
Severity: enhancement → normal
It's a new feature; word-wrap predates the spec, but overflow-wrap does not. It's still trivial, and we should do it when the spec reaches CR.
Severity: normal → enhancement
Here's a patch. I'm not sure if I went too far with the renames/comment changes here, but they seemed reasonable given that overflow-wrap is now considered the property proper in the spec.

Here are the tests. I'm not sure if the file names for the new refrests should be re-numbered or kept to match the corresponding word-wrap tests they were copied from.

This should get a https://wiki.mozilla.org/ReleaseEngineering/TryServer run once the patch is revised before it lands. needinfo? me and I can push it for you.

Comment on attachment 8755648 [details] [diff] [review] 955857-add-tests-for-css-overflow-wrap.diff overflowwrap-04 and overflowwrap-05 should use overflowWrap rather than wordWrap . There's also no need to copy the -ref files (even though you did change some of them), but you need to fix the manifest accordingly. For the ones where the -ref file uses overflow-wrap (4, 5, 8, 9, I think), you could do an == test between the two tests instead of having a second copy of the reference. r=dbaron with those things fixed, although I should probably look at the revisions, so not marking as review+

It was only tests 4 and 9, after a second look. Turns out that 8 was really testing the output of overflow:scroll against the results of word-wrap, so I don't suspect it's worth duping that one. The rest I adjusted as you suggested.
Here's the revision with the re-ordering. needinfoing you as requested.

One failure so far that seems related, in mochitest-devtools-8: INFO TEST-UNEXPECTED-FAIL | devtools/client/inspector/rules/test/browser_rules_completion-new-property_02.js | Number of suggestions match - Got 17, expected 16 Given that it's testing the devtools autocompletion for the number of properties that start with "o", I think it's just fine to bump the number to 17. I'll test that locally without bothering with another try run.

No review.
Thanks for the try run. It seems to have completed now, and I can't see the other two failures being related to this patchset. (Also thanks for fixing the other failure). Let me know if there's anything else I should deal with before this can be considered for landing (whenever that becomes appropriate).
comment 12 (which is script-generated) says I already landed it on mozilla-inbound, which is merged to mozilla-central once or twice per day.
I've moved the word-wrap page to https://developer.mozilla.org/en-US/docs/Web/CSS/overflow-wrap [And adapted it of course] and updated: https://developer.mozilla.org/en-US/Firefox/Releases/49#CSS
