LibWeb/DOM: Update "inner invoke" to current spec

Two differences:

1. An extra step inserted to record timing info, which we don't yet
   implement.

2. The last step in the loop breaks instead of returning the value
   directly. (But this is functionally the same, as the following step
   does return that value.)

(Also removed the duplicated part of the comment in step 11 née 10.)

So, there's no actual change in behavior.
