Did you delete this assignment entirely? I see you are calculating it inside ComponentDidUpdate but there is no assignment to this.headerEmojis there. I see it's used in CategoryShortcutBar, and because of that it's not visible now

Could you explain to me why we need this? I'd just like to understand.

We are calculating allEmojis whenever frequentlyUsedEmojis are changing. Since we are not directly using the frequentlyUsedEmojis value in the memo hook, it gives lint error.

The EmojiUtils.mergeEmojisWithFrequentlyUsedEmojis() function uses the frequentlyUsedEmojis value internally by subscribing to onyx in EmojiUtils.
