[Bug-Candidate]: custom errors in require statements trigger error when used inside a modifier

[Sergei-Liakh]

Describe the issue:

Custom errors within require statements work correctly when used inside functions, but they trigger an error when placed inside a modifier.

Code example to reproduce the issue:

pragma solidity 0.8.27;

error SomeError();

contract Test {
    modifier onlySomething() {
        require(false, SomeError());
        _;
    }
}

Version:

0.10.4

Relevant log output:

ERROR:ContractSolcParsing:Missing modifier Variable not found: require(bool,error) (context Test src/Test.sol#5-11 (1 - 0))
