        There’s an minor issue of how to display word-wrapped lines
        while the window is scrolled horizontally.  Currently,
        horizontal scrolling simply inhibits word-wrap.

        Otherwise, I have very little knowledge of the Emacs display
        engine implementation to actually code support for such a
        property myself.  However, should it be implemented, I’d happily
        update my patch for #19462 to use that so that non-flowable
        content gets marked as such.
