PETA paying for animal testing?

This seems a very unusual move from PETA (People for the Ethical Treatment of Animals) they are offering to pay $1000000 to the first group to develop commercially viable vat-grown meat.

While it is understandable why PETA would champion this (since vat meat would remove in principle many (weak) justifications for meat eating.
However it seems in contrast with many of their previous stands, the most obvious issue being that this will almost certainly involve animal testing... Especially since they want it to taste the same as existing meat...
