Original report: b/398194709#13

This crash happens any time I return from inside a key block before reaching a child Composable.

Here's a set of minimal cases that do and don't trigger the crash:

@Composable
fun Broken1() {
    key(1) {
        return
        Text("unreachable")
    }
}

@Composable
fun Broken2() {
    key(1) {
        Text("reachable")
        return
        Text("unreachable")
    }
}

@Composable
fun Broken3() {
    key(1) {
        return
        Text("unreachable")
        Text("also unreachable")
    }
}

@Composable
fun NotBroken1() {
    key(1) {
        return
    }
}

@Composable
fun NotBroken2() {
    key(1) {
        if (false) {
            Text("unreachable")
        }
    }
}

@Composable
fun NotBroken3() {
    key(1) {
        Text("reachable")
        return
    }
}

Note that in my code, the return is inside a conditional (of the sort val thing = optionalThing ?: return) above a single child composable (an AndroidView).
