one way to go might be:
provide a flexible internal API which can return logical word break before or after space depending on passing-in parameter.
expose the  public API by passing the correct parameter so that the logical word break matches native platform's.

--webkit-visual-word should use this internal API,
so, some of the cases where word break in a box is collected will not be needed, instead, we could just use logical word break by passing in correct parameter depends on box and block's directionality.
