How do I stop iPadOS from thinking a drag is for a new window?

On iPadOS 26, dragging my draggable() View near the edge of the screen is causing a new window to open.

This doesn't happen with .onDrag on iPadOS 26, or with either .draggable() or .onDrag on iPadOS 18.5.

This is not something I'm intending to offer in my app, and doesn't really make sense. Is there any way to prevent this from happening? Is this a bug? I couldn't find any new documentation.

The thing being dragged: the "Font" rectangle on the right side of the screen, which represents an item in my app that is reorder-able when multiple are present.
