Reviewed by Ryosuke Niwa.

Source/WebCore:

When the selection extends from first paragraph to start of next
paragraph then Justify command is applied to both the paragraph,
Instead it should be applied only to first paragraph.

paragraph to ensure that only the first fully-selected paragraph should
be justified when justifying the selection.
