# When highlighting a node, also consider the loose tokens around it.
	#
	# Loose tokens are tokens discarded from the AST but attached before
	# or after some non-loose tokens. See `Token::is_loose`.
	#
	# When this flag is set to `true`, the loose tokens that are before the
	# first token and after the last token are also highlighted.
	#
	# Default: false.
