        Test: editing/selection/extend-forward-by-word-over-non-editable.html

        Change all instances of honorEditableBoundaryAtOrAfter to honorEditableBoundaryAtOrBefore and vice versa in the
        functions which determine the end/start of words/lines/sentences in visible_units.cpp.

        This fixes the bug where moving forwards by a word over a non-contenteditable region would place the cursor
        inside that region, and then get moved back to the start of the word due to honorEditableBoundaryAtOrBefore.
        The cursor is now moved to the end of the region (which is effectively a noop in this case).

        * editing/visible_units.cpp: Change all instances of honorEditableBoundaryAtOrAfter to
        honorEditableBoundaryAtOrBefore and vice versa.
