Okay.

heehee. Yes, I see now. I'll see if I can come up with an example where it matters.

I'm not sure that preserving it is doing authors any favors. Is this implemented anywhere, and do we know of authors who have used this mechanism to un-break lines? I'd like to hear what their expectations / desires are.

Can't we do better somehow? 😕

🤷🏻‍♂️ Okay.

Ah, I see. It's pretty unfortunate we have to have special cases for Unicode. Presumably other text engines don't have these special cases, which means other editors should have the special cases, or CSS should adopt whatever behavior the other editors have.

Therefore, either:
1. These special cases should be moved into Unicode, allowing the behavior to be shared among all text editors, or
2. We should find a new way of solving this problem
