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

Despite what is alleged in the link, all major browsers do honor 'display: none' on a BR element, and have done so for a long time. I use that fact frequently when I have to style someone else's HTML, and get rid of line breaks where I don't want them. 

Safari, at least, also honors 'line-height' and 'font-size', and if you set 'content' to a string (even to '\A'), then it seems to honor all the other property values, including 'display' values (but it doesn't actually visibly change the content).

I think that WHATWG should change its incorrect definition, and should say that it is treated as though it was a glyph, and not as an element, except for a limited set of properties and values.
