combineWithAllErrors doesn't narrow down type of items in list

[Sebastian-Nielsen]

	if (combineWithAllErrors([ result1, result2, result3 ]).isErr()) {
	        console.log("some error")
		return err();
	}
	
	// We know for sure know that result1, result2, and result3 are ok:
	result1.value; // TS2339: property 'value' does not exist on type 'Result' 
	
	// ^^ it seems typescript doesn't know?

I am forced to do:

	if (combineWithAllErrors([ result1, result2, result3 ]).isErr()) {
	        console.log("some error")
		return err();
	}
	
	if (result1.isErr()) {    
		return 1 as any;
	}
        console.log(result1.value); // works

Can we do something about the fact that combineWithAllErrors doesn't narrow down the type for the items in the provided list?
