The issue was that the `handle_left`, `handle_right` and `position` attribute are updated one after another and the input field is evaluated again for each attribute. If the handle positions are updated first, then the tangent will change in consecutive evaluations. The fix is to set the three attributes at the same time and to evaluate the inputs only once.
