There are few emojis that are missing like ninja, militiary helmet, anatomical heart, asterick, keycap 0-9 (keycap 10 is rendering properly), beaver, beetle… most of them are missing. I have cross checked with default windows emoji insertion (win + .), emoji shortcode, emoji search. But none of them working.
(Also i feel there are many emoji that look complete black and white like beach_holiday. Emoji is good way for interactive writing. Please think about it)
