Generic stability and connected-component equality for definably compact groups over the Laurent series field

Let GG be a definably compact group defined over C((t))\mathbb{C}((t)). Write G0G^0 for the connected component and G00G^{00} for the smallest type-definable subgroup of bounded index.

Conjecture on definably compact groups. The group GG is generically stable, and

G00=G0G^{00}=G^0

is a finite-index subgroup of GG.

This is the revised conjecture attributed in the source to the work cited as cite{LY}; the source provides no resolution evidence.
