In CSS3 white-space-collapse and text-wrap are orthogonal, so while it might
not be 100% obvious, it could actually be useful for
white-space-collapse:discard to work with text-wrap:normal to hide all
white-space but continue using it for breaking purposes. It might make more
sense to name the white-space-collapse value 'hide' instead of 'discard'.

I do think it's desirable to allow collapsed-away whitespace to create break
opportunities. Otherwise we have the situation that
<span style="white-space:nowrap">Hello</span> Kitty
has a break opportunity but adding a space in the span to get
<span style="white-space:nowrap">Hello </span> Kitty
makes that break opportunity go away. It's rare for adding text to remove
line breaks, and would definitely shock users in editing situations.
