"Add to mixin config" quick fix does not detect Fabric side annotations

[Hubry]

When you create a mixin class on Fabric targetting a class marked with @net.fabricmc.api.Environment(net.fabricmc.api.EnvType.CLIENT), the quick fix suggests putting it on the common side. In Forge environments it suggests putting it on the client side.
From a cursory glance, it seems like the mixin inspection uses SideAnnotation.kt, which is only aware of Forge's annotations.
