We study microwave absorption of fractional quantum Hall droplets with quasiparticle tunneling across a quantum point contact. Using a nonperturbative path-integral Monte Carlo method, we compute finite-temperature responses and identify measurable resonance shifts and broadening from tunneling-induced renormalization of edge excitations.
