Tax loss harvest tool is taking into account NFTs with the same token symbol (i.e. ETH, ENS, etc.) in its tax loss harvest recommendations. This means that a user may see a prompt to harvest losses for a token that would not yield a capital loss.
e.g. This is especially highlighted with the ENS token and ENS domains. If a user was airdropped ENS tokens and set their cost basis to $0 they should not be prompted to harvest their ENS tokens. BUT if they bought an ENS domain that cost basis will be tracked and accounted for in the harvest recommendation because we are mapping to the same token symbol and disregarding the ENS domain (NFT) ID #.
