bug: uint should not be used for method signature encoding?

https://github.com/ethereum/tests/blob/1c23e3c27ac53b794de0844d2d5e19cd2495b9d8/src/GeneralStateTestsFiller/Cancun/stEIP1153-transientStorage/15_tstoreCannotBeDosdFiller.yml#L27C16-L27C44

0x883264e8 is the keccak of doCall(uint). While the solidity spec claimed

uint, int: synonyms for uint256, int256 respectively. 
For computing the function selector, uint256 and int256 have to be used.

So is this correct? Should use doCall(uint256) for signature?

hm, but it seems to still work when calling solc generated contracts
