L2StandardERC20 not being initialized correctly

[0xnakato]

Hello, I'm testing the ERC20 permit feature with USDC and DAI on the zkSync Era testnet. However, a permit signature created with the token name will not work and returns the error Invalid signature.

And it looks like the bridge token contract is not correctly initialized the ERC20PermitUpgradeable and only ERC20Upgradeable is initialized.

https://github.com/matter-labs/era-contracts/blob/main/zksync/contracts/bridge/L2StandardERC20.sol#L82

The DOMAIN_SEPARATOR() of the testnet DAI token will return 0x630ae2e0feb87df0136547b778ed1ad7bb1fdc555ac24d3a61b55432a339fe12 which is the exact value of the uninitialized domain separator.

Example codes to generate the same/uninitialized domain separator
