3D widgets not affected by depth of field?

Is there a way to make sure my 3D widgets (spawned in-world) are affected by the DOF post process? As it is right now, they all appear crystal clear regardless of the DOF effect. Certainly, this is possible, right?

I should add that I’m ONLY having this problem with Transparent Blend Mode 3D widgets. Anything set to Masked blurs, as expected.
