I was looking at the kotlin standard library, and I came across this comment on the function List<T>.lastIndexOf(element: T) :

@Suppress("EXTENSION_SHADOWED_BY_MEMBER") // false warning, extension takes precedence in some cases
public fun <@kotlin.internal.OnlyInputTypes T> List<T>.lastIndexOf(element: T): Int {
    return lastIndexOf(element)
}

"false warning, extension takes precedence in some cases"
In kotlin.collections, list is defined with this method:

public interface List<out E> : Collection<E> {

    /*Other things*/

    public fun lastIndexOf(element: @UnsafeVariance E): Int

    /*Other things*/
}

Why is this a false warning? When does the extension ever take precedence?
Thanks in advance!
