[IntersectionObserver] Get rid of spurious console warning.

[IntersectionObserver] Get rid of spurious console warning.

developers when they called observe() on a target without adding it to
the DOM tree.  However, now that observe() always results in an
initial notification, this console warning becomes more noisy than
useful.
