Look if we need to add a fallback for `word-break`

[XhmikosR]

Currently we are using word-break: break-word; in various places like code.

This isn't a standard property, at least not yet.

See if we need to provide a fallback.

See #28381 for a possible solution.

It's not a browser bug... this isn't a standard yet.

Browser support, is I guess what I meant. I don't know if we should have a label for that or not, but that's another issue.

[XhmikosR]

We don't, thus how I actually noticed the issue. Using vnu.jar's web interface, which can also lint CSS, I saw the break-word errors and then looked into it.

IMO we shouldn't use non-standard properties when possible, and when we do we need to make sure we have fallbacks.

Because something works in Chrome/Chromium, certainly doesn't mean is standard, and we shouldn't endorse this.

/CC @twbs/css-review, not sure if this is still applicable.
