When fragmenting monolithic replaced elements, e.g. images, it would in many cases be useful to have functionalities similar to orphans and widows, to avoid splitting off too small parts at the beginning or end.

Our current approach is actually using the orphans and widows properties, multiplying their values with the used line-height of the image box, causing breaks to be avoided or happen earlier, as in text.
