Update the two remaining tests for the fast text autosizer

Update the two remaining tests for the fast text autosizer

This patch updates the two remaining tests from the old text autosizer
for the new fast text autosizer.

cluster-list-item.html has been modified to not show the list bullets
and a comment has been added about why.

oscillation-javascript-fontsize-change.html has been updated to not
be a shrink-wrapped div. This changes the test significantly but I
think the test coverage may still be worth it.
