We can split the sentence from the two sections in the spec into a section
for SVG to refer to if it's desired.

But is the requirements for text-on-path the same as break-all? If you
place them on a path, they can keep the shape, but each shape are not
really connected unless the shape is a line, no? Does Gecko do something
special to connect them?
