Safari CSS word-break: keep-all; is not working

Question

I see that in the Safari browser the CSS word-break property which I need is not being used. Why ?

Answer 1

Update : Safari now supports keep-all as a value. As of Safari 9.

---

word-break property is partially supported in Safari, i.e it only supports word-break if you use break-all as a value and not keep-all...

As you can see here (Read the note at very bottom) which says

Note: Partial support refers to supporting the "break-all" value, but not the "keep-all" value.
