Negative slice end produces oversized output

Medium Severity

When maxLength is 1 or 2, maxLength - 3 is negative, and Array.prototype.slice treats negative end indices as offsets from the array end (unlike String.prototype.substring, which clamped them to 0). The result keeps almost all of the original code points and appends '...', producing output far longer than maxLength and even longer than the input string.
