Yeah.. People tend to forget that her body isn't exactly 'asian'. Not too mentioned she's also part Otherworld.
I think after the retcon and all, the chronology is:
1. Human/Otherworld/Mutant-white -> Until the Siege Perilous. I'll call it Original
2. Human/Otherworld/Mutant-Mixed Asian/White -> After body swap/splice. This body becomes her Default form.
3. She Dies
4. Default+ some enhancement -> After being resurrected by Jamie
5. Temporary back to Original-mixed body (Revanche's) - After being plucked out of her Default+ body - by Red Queen
6. Back to her Default+ body -> After the fight with Dazzler
7. Still in her Default+ body -> Even after being offered by Jamie to to back to her Original body. She's tired of being manipulated
8. Still in her Default+ body -> Even after being offered by Cassandra to surrender to her Mummundrai's (presumably her in Original body).
The body/race issue has been addressed so many times before. She even stated she'll not tolerate any tempering/manipulating to her body. It's just enough.
