Fix flaky collapse-pre-linestart-1.html test

The above test is flaky due to the editable region not having focus on
occasion, leading to differences with the expected test baseline, which
does have focus. The test ref explicitly calls .focus() to focus the
editable region, which guarantees the presence of the focus ring prior
to test completion. The actual test does not call .focus(), which means
there could be a race between the browser establishing focus and test
execution completing. To fix this, the collapse-pre-linestart-1.html
test is being updated to call .focus() on the editable region.

The same pattern is observed in collapse-pre-linestart-2.html, thus
that test is also being updated herewith.
