This issue is due to missing functionality in iproute2. Upstream commit 69629b4e43c4 from the iproute2 git repo adds the requisite functionality to fix this. Upstream 0486388a877 is required as a prerequisite for the target commit. Part of cfad32569f is also necessary to add the appropriate value to an enum. Specifically, the addition of SEG6_LOCAL_VRFTABLE to the SEG6 enum in include/uapi/linux/seg6_local.h.

This issue has gone on Jammy+, but still visible on Focal 5.15 variants.
