While letter-spacing should not break Arabic cursive connection, it
probably *should* break optional stylistic ligatures such as lam-meem
that some fonts may use by default. Only mandatory ligatures (i.e.
lam-alef) that are a fixed requirement of the script's shaping behavior
would be expected to be preserved in letter-spaced text.
