  In a recent article, Kwon et al. [Nature (London) {\bf 600}, 64 (2021)]
revealed nonuniversal dissipative dynamics of quantum vortices in a fermionic
superfluid. The enhancement of the dissipative process is pronounced for the
Bardeen-Cooper-Schrieffer interaction regime, and it was suggested that the
effect is due to the presence of quasiparticles localized inside the vortex
core. We test this hypothesis through numerical simulations with time-dependent
density-functional theory: a fully microscopic framework with fermionic degrees
of freedom. The results of fully microscopic calculations expose the impact of
the vortex-bound states on dissipative dynamics in a fermionic superfluid.
Their contribution is too weak to explain the experimental measurements, and we
identify that thermal effects, giving rise to mutual friction between
superfluid and the normal component, dominate the observed dynamics.
