There was a problem hiding this comment.
Confirmed against http://ecma-international.org/ecma-262/10.0/index.html#sec-binary-bitwise-operators-runtime-semantics-evaluation. Looks like it was probably a copy/paste mistake from the bitwise shift operator algorithm steps.

In the previous version ES2019, The Evaluation of binary bitwise operators utilize
ToInt32for both left and right expressions. However, the current version applyToInt32for only the left number value but useToUint32for the right number value inNumberBitwiseOp. I think it breaks the backward compatibility thus I revised the semantics ofNumberBitwiseOpto useToInt32for both left and right number values.
