OneWay binding stops working after the target manually updated

Question

I have such WPF binding code:

TestModel source = new TestModel();
TestModel target = new TestModel();

Bind(source, target, BindingMode.OneWay);

source.Attr

Not a binding expert but I believe you are running into a WPF dependency property precedence issues. It's likely that setting the value directly takes precedence over the binding value. That's why it overrides the binding.
