The transverse electron scattering response function of ${}^3\mathrm{He}$ was recently studied by us in the quasielastic peak region for momentum transfers $q$ between 500 and 700 MeV/$c$. Those results, obtained using the active nucleon Breit (ANB) frame, are here supplemented by calculations in the laboratory, Breit, and ANB frames using the two-fragment model discussed in our earlier work on the frame dependence of the longitudinal response function $R_L(q,\omega )$. We find relatively frame-independent results and good agreement with experiment especially for the lower momentum transfers. This agreement occurs when we neglect an $\omega$-dependent piece of the one-body current relativistic correction. Inclusion of this term leads, however, to a rather pronounced frame dependence at $q=700$ MeV/$c$. A discussion of this term is given here. This report also includes a correction to our previous ANB results for $R_T(q,\omega )$.
