I have javascript which check hoverin(mouse enter)

const hoverIn = (e)=>{
    console.log("check hoverin");
}

return <li>
        <img src="test.jpg" onMouseEnter={hoverIn}></img></li>

It fires hoverin when mouse moves to the image, but when clicking, hoverin does not fired.

then, I put the css tool tip on in.

const hoverIn = (e)=>{
    console.log("check hoverin");
}

return <li className={styles['css_tooltip']}>
    <span class={styles["css_tooltiptext"]}>ToolTip Text</span>
    <img src="test.jpg" onMouseEnter={hoverIn}></img></li>

css file

/* Tooltip container */
.css_tooltip {
  position: relative;
  display: inline-block;

  /*border-bottom: 1px dotted black;*/ /* If you want dots under the hoverable text */
}

/* Tooltip text */
.css_tooltip .css_tooltiptext {
  visibility: hidden;
  width: 120px;
  background-color: rgba(0,0,0,0.4);
  color: #fff;
  text-align: center;
  padding: 5px 0;
  border-radius: 6px;
  /* Position the tooltip text - see examples below! */
  position: absolute;
  z-index: 1;
}

/* Show the tooltip text when you mouse over the tooltip container */
.css_tooltip:hover .css_tooltiptext {
  visibility: visible;
}

With this script, somehow when clicking, hoverin is fired.

How can I prevent this??
