Stack overflow when assigning types with mutually recursive tuple-typed properties

[DanielRosenwasser]

interface Tree1 {
    children: [Tree1, Tree2];
}

interface Tree2 {
    children: [Tree2, Tree1];
}

let tree1: Tree1;
let tree2: Tree2;
tree1 = tree2;
tree2 = tree1;

Basically either of the last two assignments trigger the stack overflow.

The following example also triggers the issue. Notice that both element types in Tree2 are also of type Tree2.

interface Tree1 {
    children: [Tree1, Tree2];
}

interface Tree2 {
    children: [Tree2, Tree2];
}

let tree1: Tree1;
let tree2: Tree2;
tree1 = tree2;
tree2 = tree1;
