[css-text] Should contenteditable word-wrap: break by default

We have an interop issue that was submitted to us as a bug and it concerns contenteditable. Currently Chrome currently adds the following props by default to any element that has a contenteditable:
     word-wrap: break-word
     -webkit-line-break: after-white-space

Firefox/IE currently render the same by adding scroll bars if the length of the content overflows the input (assuming overflow: auto|scroll) if there are no spaces inserted into the editable div, if there are spaces all browsers render the same.

Here is a fiddle: http://jsfiddle.net/pfe9mj4o/1/ (just type in the input without spaces)

I am not passionate on this one way or the other, but would just like to get the opinion of the group to determine if FF/IE should change to match Chrome or vice-versa.

Thanks,
Greg
