I think that sounds like a good compromise and a lot better than having to
add zero space characters as would otherwise be the only way around this:

a<span class="outer" cE=false>&#8203;<span cE=true>b</span>c</span>d

I can't think of any circumstances in which one may need to use the inline
css style yet still want this behavior.

Agreed. I sometimes feel that certain points have been forgotten, but I
don't want to constantly repost here as that would just spam the list.
