Coverity points out that the usage of `this` is suspicious in the `sizeof` expression here: https://searchfox.org/mozilla-central/source/js/src/builtin/Promise.cpp#4322

`this` is a pointer, if the author really intended to use `this`, wouldn't it make more sense to use `void*`, so that the intention is clearer? If it is indeed a typo, then I guess the fix is to use `*this` instead of `this`.

yes, it should be *this, or just "PromiseLookup".
ArraySpeciesLookup::reset has the same issue.

are you going to post patch?

Yes, I will also fix the array one here if that is fine with you.
