Fix for #8638 (comment). Part of #8544.

Comment thread Contributing.md Outdated
- [ ] Binary writing added in src/wasm-stack.h and src/wasm/wasm-stack.cpp
- [ ] Support added in various classes inheriting OverriddenVisitor (and possibly other non-OverriddenVisitor classes as necessary)
- [ ] Support added to src/tools/fuzzing.h
- [ ] If adding tests before fuzzing support, mark the test as unfuzzable first.

Kind of weird github lets you request a review for a PR that is marked draft and even has a button "ready for review"...
