>
> The UnifiedHighlighter's DefaultPassageFormatter (mostly unchanged from the
> old PostingsHighlighter) will format overlapping matches by closing a tag and
> immediately opening a tag. I think this is a bit ugly structurally and it
> ought to continue the tag is if the matches were merged. This is extremely
> rare in practice today since a match is always a word, and thus we'd only see
> this behavior if multiple words at the same position of different offsets are
> highlighted. The advent of matches representing phrases will increase the
> probability of this, and indeed was discovered while working on LUCENE-8286.
> Additionally, and related, OffsetsEnums should internally be ordered by the
> end offset if the start offset is the same.
