Summary: IndexType::kBinarySearchWithFirstKey + BlockCacheLookupForReadAheadSize enabled => FindNextUserEntryInternal assertion fails or iterator lands at a wrong key because BlockCacheLookupForReadAheadSize moves the index_iter_ and in internal_wrapper.h, result_.key didn't update and pointed to wrong key. Also ikey_ was also pointing to iter_.key() instead of copying the key.
