The flows in both problems are closely analogous to the displacements in a Hertzian elastic contact. We exploit that analogy to provide both a scaling argument and a calculation for the early growth of the contact radius $a$ with time, namely $a=(3 \\pi \\gamma R^2 t/(32 \\eta))^{1/3}$. (This result is complementary to the well-known Tanner law for spreading, $a \\sim t^{1/10}$, which holds in the regime of low contact angles.)
