  We show that the "defective" terms in the expression that Dondera [Phys. Rev.
D 98, 096008 (2018)] obtained for the momentum of the retarded field of an
accelerating point charge are mathematically well justified. The repair should
not be sought in assigning an accelerating "bare" charge ad hoc compensating
attributes. We advance a conjecture, supported by published work, concerning
the Hadamard finite part of the divergent integral for the retarded-field
momentum in question.
