Yeah, I missed that somehow.  `pre-line` looks close but collapsed inter word spaces; `pre-wrap` doesn't, but its wrapping behavior is different.  I get the impression that `pre-wrap` is the one you want, but perhaps not correctly working Chrome?  Looks like browsers are disagreeing; Firefox is doing it differently (with `pre-wrap`):

That's done almost everywhere, just try it in the comment box here on Github for example.  Type sufficient text to reach the edge of the box, then type a lot of spaces.  They seem to "disappear", and they don't appear when the text reflows.  If you then cursor back, the cursor won't appear until you passed all the spaces you typed; or if you break the line in some other place, all those spaces are still there. It feels odd, but I think it is not a bad way to handle this kind of thing.

The example of MS Word that Nir showed also shows that the extra spaces just go past the margin.  Photoshop does the same (it's in one the tickets).
