Please open an issue with them. This is valid es2015.

The issue is that IE 11 doesn’t support Object.entries(…) and needs a polyfill.

Also, IE should be throwing a TypeError in this case.

Plus, we don't support browsers at the moment. Any browser support is entirely undocumented, unsupported and the burden of making it "work" is on the consumer.
