@mfoerste4's PR 2185 uses an intermediate device_uvector instead of a raft::device_matrix because the matrix's size() isn't suitable for the copy here.
That PR is targeting branch-24.02. Should we merge that PR into 24.02 and rerelease RAFT, or should we merge that PR into this one and include it in 24.04?

This workaround was accidentally reverted during this commit but the additional memory copy is needed for proper results in CUDA 12.2-12.4.
