Graph widget in Filter 1, 2 lights up as drop zone for modulators

When dragging a modulator into the Filter 1 and 2, the whole graph widget lights up, despite not being a valid target. This obscures that the sliders around the graph, which indeed are modulable, are also lit

The similar filter widget in the FX section does not have this behavior
