	if isinstance(choice.title, list):
	tokens.extend(choice.title)
	elif selected:
	tokens.append(
	("class:selected", "{}{}".format(shortcut, choice.title))
	)
	elif index == self.pointed_at:
	tokens.append(
	("class:highlighted", "{}{}".format(shortcut, choice.title))
	)

maybe merge class:highlighted to every item better.

example:
title = [ ("class:a", "user"), ("class:b", "age") ]
after merge:
title = [ ("class:a class:highlighted", "user"), ("class:b class:highlighted", "age") ]

@ThanrayTian that sounds reasonable - do you mind proposing a fix in a PR?

Just openned this PR as maybe a starting point for a fix:

#362

Edit: This was my particular use case: I need custom styles on a select with Choice but the highlighted only works when title is a string
