withThrowingTaskGroup(of:returning:isolation:body:) transpiled incorrectly

Issue

I have a function with the following Swift code:

var allProducts: [FNCProduct] = []

try await withThrowingTaskGroup(of: [FNCProduct].self) { pageProductsTaskGroup in
    // Some irrelevant code

    for try await pageProducts in pageProductsTaskGroup {
        allProducts.append(contentsOf: pageProducts)
    }
}

return allProducts

This gets transpiled to the following Kotlin code:

var allProducts: Array<FNCProduct> = arrayOf()

withThrowingTaskGroup(of = Array::class) { pageProductsTaskGroup ->
    // Some irrelevant code

    for (pageProducts in pageProductsTaskGroup.sref()) {
        allProducts.append(contentsOf = pageProducts)
    }
}

return@l allProducts.sref()

I'm getting an error from the compiler that refers to the following line:
allProducts.append(contentsOf = pageProducts)

Argument type mismatch: actual type is 'skip.lib.Array<CapturedType(*)>', but 'skip.lib.Sequence<funico.module.FNCProduct>' was expected.

Proposed solution:

I think this:

withThrowingTaskGroup(of = Array::class)

needs to change to this:

withThrowingTaskGroup(of = Array<FNCProduct>::class)

Start by reproducing the issue with the Swift withThrowingTaskGroup(of:returning:isolation:body:) example and inspect the generated Kotlin call using Array::class. The fix is complete when the generated type preserves FNCProduct and the append(contentsOf:) line compiles without the reported type mismatch.
