According to rule 4 at https://drafts.csswg.org/css-text-3/#white-space-phase-2, "If white-space is set to pre-wrap, the UA ... may also visually collapse the character advance widths of any that would otherwise overflow." I think that's what Firefox is doing here.

Umm, that's true; it seems the spec accepts both behaviors.

OK, closing this as invalid -- it's not a bug after all, right? (Unless you think the spec should be changed to disallow this behavior, but that would be a discussion for the CSS WG first.)

Comment 6

[Javier Fernandez]

I agree on closing this bug.
