import { parse } from 'twemoji-parser';
const  entities = parse(`
1F3F3 FE0F 200D 26A7 FE0F                              ; fully-qualified     # 🏳️‍⚧️ E13.0 transgender flag
1F3F3 200D 26A7 FE0F                                   ; unqualified         # 🏳‍⚧️ E13.0 transgender flag
1F3F3 FE0F 200D 26A7                                   ; unqualified         # 🏳️‍⚧ E13.0 transgender flag
1F3F3 200D 26A7                                        ; unqualified         # 🏳‍⚧ E13.0 transgender flag
`);

Expected behavior
All unqualified emojis should be parsed correctly.
