Return multiple values

[webersson]

Description

I'm trying to return multiple values with a simple function:

 function testMulReturn() public view returns (address, uint) {
       return (msg.sender, 777);
 }

Calling:

ContractInstance.methods.testMulReturn().call().then(function(result) {
	console.log(result);
})

Returns { '0': '0', '1': 'x' }

Calling a function with just one return value e.g

 function testMulReturn() public view returns (address) {
       return (msg.sender);
 }

...is working as expected.
Returns: 0x1b42dC2F1A3A548A5e6D76c19cCd768aDCa37815

Why is this happening? Any help much appreciated.
