Im seeing:

Modifier factory functions must use the receiver Modifier instance

for the snippet below. Yet both clickable/pointerInput does

this then modifier

under the hood. Bug, or am I missing something?

private fun Modifier.interactions(
    onClick: (() -> Unit)?,
): Modifier {
    return when {
        onClick != null -> clickable(
            onClick = onClick,
        )

        else -> pointerInput(Unit) {}
    }
}

this then

is using the receiver

Modifier
