Histogram not updating when clicking down the history stack
When clicking down the history stack the image updates but the histogram doesn't (always).
Open an image, observe the histogram, open the history and click on orientation. The image changes, but the histogram remains the same.
Next, open basic adjustments and do an auto adjustment. Click on base curve in the history stack and the image changes but the histogram doesn't. Then click on orientation and the image changes and the histogram changes.
Clicking up the history stack appears to work correctly.
