Comment 5 for bug 2047021

I see "vertical buttons" issue is the same on Pinta/Ubuntu.

I downloaded the latest release from master repository: https://github.com/PintaProject/Pinta/actions/runs/7278443090/artifacts/1127062967

1. Create new image 800x600.
2. Paint it somehow, I used Paint Bucket and fill it with red color.
3. CTRL+A and CTRL+C to copy image.
4. Close image without saving e.g. CTRL+W
5. Create new image 640x480.
6. CTRL+V to paste the image. Dialog with vertical buttons appear. (If I click on Expand canvas, now crash does not appear any more). See attachment.

It looks to me some setting of this dialog are arranging buttons vertically instead of horizontally.
