I wouldn't call that a bug :) You could consider using a "lifting function" approach, where you impose zero Dirichlet boundary conditions, and then solve for u_hat = u - g_BC, where g_BC is a (possibly time-dependent) lifting function that satifies the non-zero boundary condition that you want.
Then you recover the solution u by u = u_hat + g_BC. That would work without any changes to the DirichletBoundary infrastructure.
