Date: November 15, 2021
When ERC1155 tokens are minted, a callback is invoked on the receiver of those tokens, as required by the spec. When including the ERC1155Supply extension, total supply is not updated until after the callback, thus during the callback the reported total supply is lower than the real number of tokens in circulation.
