Solang loads vectors from storage incorrectly

      contract Testing {

    struct PaddedStruct {
        uint128 a;
        uint8 b;
        bytes32 c;
    }

    PaddedStruct[2][3][] stor_arr;

    function addData() public {
        PaddedStruct memory a = PaddedStruct(56, 1, "oi");
        PaddedStruct memory b = PaddedStruct(78, 6, "bc");
        PaddedStruct memory c = PaddedStruct(89, 4, "sn");
        PaddedStruct memory d = PaddedStruct(42, 56, "cn");
        PaddedStruct memory e = PaddedStruct(23, 78, "fr");
        PaddedStruct memory f = PaddedStruct(445, 46, "br");

        PaddedStruct[2][3] memory vec = [[a, b], [c, d], [e, f]];
        stor_arr.push(vec);
    }

    function getThis() public view returns (uint32) {
        PaddedStruct[2][3][] memory arr2 = stor_arr;

        return arr2.length;
    }
}
  

Calling getThis after addData returns 6, instead it should return 1. If we modify stor_arr to PaddedStruct[2][2][] stor_arr and do all the necessary changes, addData returns 4. I think we are incorrectly merging the first two dimensions into one.

uint16[4][2][] simple_arr;
    function multiDim() public returns (uint32) {
        uint16[4][2] memory vec = [[uint16(1), 2, 3, 4], [uint16(5), 6, 7, 8]];
        simple_arr.push(vec);
        
        uint16[4][2][] memory mem_vec = simple_arr;
        return mem_vec.length;
    }

This returns 8 🤨
