Invalid scroll event for iView component input [type = "textarea"]

Native textarea scrolls can be done with @ scroll ,
but the Input component in iView does not seem to provide on-scroll instruction. What should I do
?

you can bind scroll events in mounted to handle

.
mounted: {
    // $refsdom
    this.textArea = this.$refs.viewTextArea;
    // domscroll
    this.textArea.addEventListener('scroll', () => {}, true);
}
