Inconsistent Zoom Out behavior using CTRL + Mouse Wheel Scroll Down

Description Previously, I always use CTRL + Mouse Wheel to quickly zoom in and out of images in Pinta.

But right now after compiling latest from source with pinta-git package on Arch Linux AUR, zoom out behavior is inconsistent, either:

• It zooms out the image just fine
• It scrolls across the entire image height (Y-axis) first before zooming out

---

To Reproduce

1. Open Pinta
2. Paste any image that have quite decent height (I just took screenshot of Pinta's README.md, 1455x996 image)

<img width="242" height="166" alt="Image" src="https://github.com/user-attachments/assets/c620a622-0757-4366-ab60-70a42655681a" /> <br><br>

3. Zoom in anywhere on the image using CTRL + Scroll Wheel Up
4. Release CTRL
5. Vertically scroll the image (up/down) a bit using the scroll wheel (avoid scrolling to the vertical edges)
6. Zoom out using CTRL + Scroll Wheel Down
7. The Problem: Pinta tries to vertically scroll down the image before attempting to zoom out

Additional Info Here's a video showing the issue (Vertically scrolling the image before zooming out):

Here's a video showing the usual behavior (I didn't vertically scroll the image this time):

Tried to recompile from source again just in case of a bad compilation, still same issue.
