[Bug] Stack Images Reset Horizontal Flip on Scroll after Being Flipped Horizontally and Vertically

[pnewhook]

Describe the Bug

Flipping MRI/CT stacks vertically and horizontally in a stack viewport loses flip after scrolling. We've found this issue in our application, and we believe it's reproducible in the Stack API example.

Steps to Reproduce

1. Visit https://www.cornerstonejs.org/live-examples/stackapi
2. Flip both horizontally and vertically
3. Click on Next Image
4. The next image is no longer flipped horizontally

The current behavior

Individual images in the stack lose the horizontal flip after scrolling. The vertical flip flag is now false, and the image is instead rotated 180 degrees.

The expected behavior

All images in a stack should be flipped horizontally and vertically. If only a horizontal or vertical flip is selected, the flip is visible on the full stack when scrolling.
