The component in EntityRenderState#nameTag is always set from EntityRenderer::getNameTag, RenderNameTagEvent$CanRender::getContent is never used.
Also on a side note it is no longer possible to render name tags for entities more than 64 blocks away due to RenderNameTagEvent$CanRender only being called when entity.distanceToCameraSq < 4096.0, which wasn't the case before 1.21.2.
Before only the name tag renderer would check the distance, and by cancelling the event and rendering the name tag yourself it was possible to bypass the distance check.
