It's horrific. :(
At first glance there are at least two others from this year that I know of:
Mira (5 Apr 2020 - Cilincing, Jakarta Utara, Indonesia)
Vicky dos Santos (28 May 2020 - Itu, São Paulo, Brazil)
The latter case was very heavily reported in the Brazilian press.
Altogether I can see nearly 60 cases reported with the keywords "burnt" or "burned" in the TDoR cause of death data, but I imagine that's a significant underestimate.
