[css-flexbox] Should <br> get lumped into a "contiguous run of text" to form an anonymous flex item?

Hi www-style,

I just noticed that the current flexbox ED says the following about
anonymous flex items:
 # ...each contiguous run of text that is
 # directly contained inside a flex container
 # is wrapped in an anonymous flex item.
http://dev.w3.org/csswg/css-flexbox/#flex-item

Notably, "contiguous run of text" is rather specific and does not seem
to include <br> elements.

However, every browser I've tested [1] *does* seems to lump <br>
elements into anonymous flex items.

Here's a testcase:
http://people.mozilla.org/~dholbert/tests/flexbox/compat_tests/anon-flex-items-1.html
(If the text "Here comes a <br> element: There it went!" is all grouped
together [with a linebreak], then <br> is getting lumped into the
anonymous flex item.)

SO: Should we change the spec to match implementations? (Maybe the
current de facto behavior is really what the spec *wanted* to say, even
though it doesn't?)  Or is the current spec text really what we want, in
which case this is a bug that needs fixing in all modern browsers?

Thanks,
~Daniel
