Multiple layers of map cause an execution error.

[Subway2023]

Version: v0.3.3: Atlantis
Description: The statement _map[1] = 2; will cause an execution error.

contract test {
    mapping(uint name1 => mapping(uint name2 => uint name3) name4) map;

    function main() external {
        mapping(uint name5 => uint name6) storage _map = map[1];
        _map[1] = 2;
    }
}

Reproduction: I set up a Solang compilation and execution environment to test the program.

solang/target/debug/vmRunNoPara test.sol test main

The execution error is as follows:
