Should "heart on fire" without VS16 count width of 2?

[fisker]

Currently "2764 FE0F 200D 1F525"(❤️‍🔥) is considered width of 2, but "2764 200D 1F525"(❤‍🔥) is considered width of 1.

Maybe only codes in https://www.unicode.org/emoji/charts/emoji-variants.html requires VS16?

Full list of emojis counts as width of 1 from https://www.unicode.org/Public/latest/emoji/emoji-test.txt
