Token amount can be underestimated when minted in more than one box

This tx mints a token into two output boxes: https://explorer.ergoplatform.com/en/transactions/79451d8c64afa7215546e8380c56bf0931e278ce08173bfe7cecd10e263fb134

Reported token amount (https://explorer.ergoplatform.com/en/issued-tokens?searchQuery=4a9d3ee47125781e5a2976e0c37862ae53e8f9ee39a26269a9c8c5d50bb05b9a) shows amount of tokens minted in first box, ignoring amount of tokens in second box.

In my opinion we should not allow such token mintings. It will probably break most other clients as well.
