One approch to fix this is to use one more dashed line with same background as of page background.
Please refer to following code (its same as of you just some changes):
import { useEffect, useLayoutEffect, useRef, useState } from "react";
import gsap from "gsap";
interface BoxItem {
label: string;
color: string;
}
interface Line {
x1: number;
y1: number;
x2: number;
y2: number;
}
const boxData: BoxItem[] = [
{ label: "Event", color: "#ff6b6b" },
{ label: "Date", color: "#4dabf7" },
{ label: "Fuel", color: "#f06595" },
{ label: "Message", color: "#51cf66" },
{ label: "Work", color: "#d0bfff" },
{ label: "Data", color: "#74c0fc" },
{ label: "Food", color: "#ffd43b" },
{ label: "Style", color: "#ced4da" },
];
