Well, I interpreted the parenthetical as maybe restricting the case of
when the default phase event handler should be fired, and so the
otherwise would capture the remaining cases (bubbling, or default-action
with no default phase).

Now that you’ve pointed it out, it seems reasonable that the “(if it
occurs)” is evaluated after noticing "default-action".
