It's up to the demangler, the info must be there in the decorated/mangled name. Demanglers sometimes choke on these complex symbols.
AFAIK MSVC also changed their lambda ABI once, including mangling. As I recall at one point it even produced some hash in the decorated/mangled name, with no way to revert it, but that was before /Zc:lambda (enabled by default from C++20).
