P: Lens Blur's Focal Range histogram doesn't update when Use Device Map is toggled
Checking and unchecking Use Device Map in Lens Blur doesn't update the Focal Range histogram.
To reproduce in LR 13.0.1:
1. Import this HEIC with a camera depth map:
2. Apply Lens Blur and click Visualize Depth.
3. Toggle .... > Use Device Map in the upper-right corner of the Lens Blur panel. Observe that the visualized depth map changes but the histogram remains the same:

The histogram should change to match the currently display depth map.
