Description tophf 2022-12-19 23:58:46 PST 
1. open browserbench.org
2. check the console

Expected: no errors
Observed: "Uncaught TypeError: Illegal invocation"

The cause is this problematic code in index.html added five years ago in bug 172049:

    if (!HTMLImageElement.prototype.srcset) {

Suggesting a possible fix:

    if (!('srcset' in HTMLImageElement.prototype)) {
