ViewBuilder():switch: midi_mapping marker only marks 2 items

Renoise 3.3.1, W10 x64

It seems I have a little GUI visual problem with the switch in a windowed tool.

To reproduce what happens:

  1. Create a window tool with a swith, for example include this swith:
  renoise.ViewBuilder():switch{
        height=21,
        width=136,
        items={"1","2","3","4"},
        value=1,
        midi_mapping=("Tools:Map 1")
  },
  renoise.ViewBuilder():switch{
        height=21,
        width=136,
        items={"1","2","3"},
        value=1,
        midi_mapping=("Tools:Map 2")
  },
  renoise.ViewBuilder():switch{
        height=21,
        width=136,
        items={"1","2"},
        value=1,
        midi_mapping=("Tools:Map 3")
  }
  1. Select Renoise window and Press CTRL + M. The switch object must be fully marked. However, it will only mark the first 2 items:

I think this does not happen with the Renoise window. So it’s probably an API problem, with the window tools and the switch object.
