Identify bugs and inadequacies in the following code which purports to implement a clock custom HTML element. class ClockElement extends HTMLElement { constructor() { this.time = Date.now(); } connectedCallback() { setTimeout(tick, 1000); } disconnectedCallback() { } tick() { this.time = Date.now(); this.innerHTML = } ${this.time} '; } Your answer should include outright bugs as well as identifying code which does not look quite right.
