Global value not restoring before sensor setup?

I have a global variable that is being restored from flash and then being passed into a custom sensor’s constructor. The problem is that the global value is not being restored until after the sensor is initialized, so it ends up passing 0 into the constructor. Looking at the Boot Priority documentation, it sounds like initial states should be restored before initializing sensors. Any ideas to make this happen?

globals:
  - id: saved_gallons_count
    type: int
    restore_value: yes

sensor:
- platform: custom
  lambda: |-
    auto wf = new WaterFlowSensor(id(saved_gallons_count));
    App.register_component(wf);
    return {wf->flow_rate_gpm_sensor, wf->gallons_used_sensor};
