Filtered data cannot be sorted

[MirjamSchr]

After applying a (Savitzky-Golay) filter to the dataset, the resulting data is consistently plotted at the bottom of the list of datasets, preventing manual sorting of the figure.

When having the following recipe:

  - kind: processing
    type: Filtering
    properties:
      parameters:
        type: savgol
        window_length: 100
        order: 2
    apply_to: 
      - dataset3
      - dataset4
    result: 
      - dataset3-filtered
      - dataset4-filtered
  - kind: multiplot
    type: MultiPlotter1DStacked
    apply_to:
      - dataset1
      - dataset3-filtered
      - dataset2
      - dataset4-filtered

the order in the resulting figure is:

• dataset1
• dataset2
• dataset3
• dataset4

It is the same when creating new datasets by addition of two datasets. The new dataset is always plotted at the end.
