Manual Tests

1. To the text that contains emojis, add italics styling, e.g. _🥰 test 😇 test 🥹_
2. Verify if the text has italics style and emojis don't
3. Verify if it still works when adding other styles around it, e.g. # *~_🥰 test 😇 test 🥹_~*
4. Verify if emojis aren't strikethrough
5. Test it with different style combinations
