JS: Useless loop on Image onerror -- what for?

I am tinkering around with some third party code and this caught my attention:

spimg[x] = new Image();
spimg[x].onerror = function () {
    var t = 1;
    while (t < 7) { t++ }
};
spimg[x].src = imageSrc;

After trying to load an image, if an error ocurrs, it just sets up an empty loop that finishes quite quickly.

What could be the use of such an error function?

it looks like it is from here, maybe: [How to read the blockadblock script?](https://stackoverflow.com/q/38067889) – Nina Scholz Feb 23 '19 at 19:05
@JanKyuPeblik You'd need to count to a whole lot more than 7 to add a delay. – Scott Marcus Feb 23 '19 at 19:05

@NinaScholz That's exactly where it's from! (I didn't take it from the post, rather, I unobfuscated it myself.) – Alpha Feb 24 '19 at 20:33
