Similar Issue to #963 but with Imageglass Version 9

I added this as a Bug because last time this appeared was on Issue #963, where it's called a bug. But it could also be a feature, if so I am very sorry, this is my first time adding an issue on Github.

To Reproduce

Steps to reproduce the behavior:

1. Set the keyboard setting for Left / Right arrows to Previous / Next Image.
2. Open an image in a folder containing multiple images.
3. Zoom in far enough to enable panning and lock the zoom ratio.
4. Press and hold (or single press for a subtle effect) the Left or Right arrow key.

Actual behavior

• The next image is displayed but retains the previous scroll position (e.g., the image doesn’t reset to the top).
• When holding the arrow key, the currently displayed image may pan multiple steps if the next image takes time to load.

Expected behavior

• The next image should always reset to display from the top, regardless of the previous scroll position.
• The program should allow seamless switching between images without retaining the prior scroll position or causing unintended panning.

@Zendkye The Left/Right arrow keys are still being assigned to the menu Navigation > View next/previous image.
You need to remove it from here, too:

// in igconfig.json
{
  "MenuHotkeys": {
    "MnuPanLeft": ["Left"], // set Left key for panning left
    "MnuPanRight": ["Right"], // set Right key for panning right
    "MnuViewNext": ["PageUp"], // only keep PageUp key here
    "MnuViewPrevious": ["PageDown"] // only keep PageDown key here
  }
}
