Example test fixing the issue adding an empty content

(In reply to comment #7)
> childrenInline() is TRUE for <br> and FALSE for <span> because in the case of <span> RenderObject::isInline() returns FALSE, which causes that RenderBlock::makeChildrenNonInline() is called inside RenderBlock::addChildIgnoringAnonymousColumnBlocks(). However, <br> RenderObject::isInline() returns TRUE.

Actually the reason why isInline() returns FALSE for <span> elements is because of they have "display:block", if you remove that line then the breaks don't work either with <span> tags.

It seems that the breaks only work for blocks and not for inline elements.

> Maybe in this case <br> elements with a region break should be marked as non-inline or something like that.

On the other hand in order to fix the issue with <br> elements is enough with adding "content: "";" in the CSS (as in the attached example). Because of before/after pseudo-elements are not applied if they don't have content. This is not needed for <span> elements because of they always have a content (at least an empty string).
