    "abstract": "We investigate the impact of gravitational wave (GW) dephasing due to gas accretion on the subtraction of massive black hole (MBH) binary signals over 4 yr of LISA data in the context of the global-fit. Based on state of the art predictions for the population of merging MBHs, we show that imperfect subtraction with vacuum waveform templates leaves a GW residual with an SNR of $3.2^{+5.4}_{-1.9}\\times \\sqrt{f_{\\rm Edd} \\langle \\dot n \\rangle/(20\\, {\\rm yr}^{-1})}$, where $f_{\\rm Edd}$ is the typical Eddington ratio and $\\langle \\dot n \\rangle$ the mean merger rate of LISA MBH binaries. We characterize the dependence of the residual on key population hyper-parameters, provide a simple fitting function and discuss detection and mitigation strategies.",
