  We show the sensitivity of groomed jet substructure measurements to the
finite resolution power of the QGP to disentangle multiple energetic partons,
as produced by QCD jets, that traverse it simultaneously. We illustrate these
effects by studying Soft Dropped observables within a hybrid strong/weak
coupling model for jet-medium interactions. By analysing Monte-Carlo-generated
jet data in heavy ion collisions, we show that the angular structure of these
type of observables is sensitive to the value of the QGP resolution length.
