Dataset order not applied to signal

[eshwen]

When specifying certain datasets as signal in a config, i.e.,

signal: '.*SVJ*.'

and a dataset order is specified for them, i.e.,

dataset_order:
    - SVJ_3000_20_0.9_peak (Pythia)
    - 'SVJ_3000_20_0.9_peak (MadGraph)'
    - SVJ_3000_20_0.1_peak (Pythia)
    - 'SVJ_3000_20_0.1_peak (MadGraph)'
    - SVJ_1000_20_0.3_peak (Pythia)
    - 'SVJ_1000_20_0.3_peak (MadGraph)'

the order in which the datasets are plotted is not the same. Presumably, they are just ordered by yield, as can be demonstrated with the following plots produced even with the above config fragments applied.
