Rationale

The EIP-712 specification supports fixed size and dynamic sized arrays.

From the spec,

The reference types are arrays and structs. Arrays are either fixed size or dynamic and denoted by Type[n] or Type[] respectively. Structs are references to other structs by their name. The standard supports recursive struct types.

Unfortunately go-ethereum in its current form doesn't fully comply with the EIP-712 standard because the signer module currently doesn't support encoding fixed size array datatypes.

signer/core: extended support for EIP-712 array types (#30620)
5b78aef 
This change updates the EIP-712 implementation to resolve [#30619](#30619).

The test cases have been repurposed from the ethers.js [repository](https://github.com/ethers-io/ethers.js/blob/main/testcases/typed-data.json.gz), but have been updated to remove tests that don't have a valid domain separator; EIP-712 messages without a domain separator are not supported by geth.
