Description
When manually cropping a scanned image, the crosshair inside the zoom bubble does not align correctly with the actual position of the corner handle.
The zoomed view seems to be offset from the touch point, making it difficult to achieve a precise crop because the crosshair is not pointing where the handle is actually located.
Scope
This issue specifically affects the Top Left and Bottom Left corners. The right-side corners appear to function correctly (or at least are not exhibiting this specific offset).
Steps to Reproduce
Scan a document or import an image.
Enter the manual cropping/adjustment screen.
Tap and drag the Top Left corner handle.
Observe the zoom magnifier bubble.
Note that the crosshair inside the bubble is offset and does not accurately reflect the corner's position on the document.
Repeat for the Bottom Left corner to see the same behavior.
Expected Behavior
The crosshair inside the magnifier should perfectly align with the tip of the corner handle being dragged, allowing for pixel-perfect adjustment of the crop area.
Actual Behavior
The crosshair in the magnifier is visually offset from the handle's location, showing a different part of the image than what is being selected.
