  We prove that a tracially continuous W$^*$-bundle $\mathcal{M}$ over a
compact Hausdorff space $X$ with all fibres isomorphic to the hyperfinite
II$_1$-factor $\mathcal{R}$ that is locally trivial already has to be globally
trivial. The proof uses the contractibility of the automorphism group
$\mathrm{Aut}({\mathcal{R}})$ shown by Popa and Takesaki. There is no
restriction on the covering dimension of $X$.
