Joins in Arabic are mandatory, and they are also broken across lines

Which is why the joining behavior is preserved even though it is broken

CSS does not prohibit such steps, but I do not think it should
prescribe them in this case. That's not what this feature is for.

Note that overflowing even "a bit" still produces scrollbars.
