Based on the context and comments in the code, we assume that its possible that there will be some leftover sell tokens, not only when users are selling unwrapped ETH but also for ERC20 tokens.
However, in the current implementation, only refunded ETH is returned (L158).
Because of this, the leftover tkoens may be left in the contract unintentionally.
