For legacy reasons, UAs may also accept ‘word-wrap’ as an alternate name for the ‘overflow-wrap’ property. However this syntax not valid.
Darned if I know what "legacy" they're talking about [w3.org] though, since I can't find the term in either 2 or 2.1.
An unbreakable "word" may be broken at an arbitrary point if there are no otherwise-acceptable break points in the line. Shaping characters are still shaped as if the word were not broken, and grapheme clusters must together stay as one unit.
I really ought to understand that, but I don't :(
Edit after looking at Fotiman's links:
Gee. It would be nice if the different parts of w3c talked to each other, wouldn't it? ;)
I suspect the reason the link isn't wrapping is that it doesn't have to. It has an alternative, which is to drop down out of the way of that image that's making things so crowded. So you'd also have to glue the link to its original location.
