explorer: SPL transfers using wrapped sol accounts are not denominated in SOL

[jstarry]

Problem

In the following transaction, inner instruction #7.1 transfers wrapped SOL but the transfer does not use SOL as a unit and doesn't include decimals: https://explorer.solana.com/tx/2rVoa1HPosx41s5AdQttx3N15pZqj6LnqPJzd76YYcnV1XaVLXasrN5tNxkrk87fHKA6BZHCbt4PoKLAwoD5LVXM

Proposed Solution

Unchecked token instructions don't carry mint metadata. We should be able to pull this in from the token delta metadata (if available).
