Invalid expression at code generation time

[FloVanGH]

After I try to compile the following code I get an internal error, encountered invalid expression at code generation time panic. In the preview the code works.

component TestComponent {
    in-out property <bool> check;
}

export component App inherits Window {
    min-width: 800px;
    min-height: 600px;
    title: "Test";

    Rectangle {
        i-test := TestComponent {}

        if (i-test.check) : Rectangle {}
    }
}

This works:

component TestComponent {
    in-out property <bool> check;
}

export component App inherits Window {
    min-width: 800px;
    min-height: 600px;
    title: "Test";

    Rectangle {
        i-test := TestComponent {}

        if (1 == 1) : Rectangle {}
    }
}

Tested with the crates release 1.1.1 and the current master.
