What is the problem?

Description

On iOS, in analysis mode, dragging a piece from the left side of the board can also trigger the native swipe-back gesture.

As a result, both happen at once:

• the piece is being moved
• the app navigates back

The arrow in the screenshot is the move indicator from piece movement, not a manually drawn shape.

Expected behavior

Dragging a piece should only interact with the board.

Actual behavior

A piece drag starting near the left edge can also trigger back navigation.

Steps to reproduce the bug

1. Open analysis mode on iPhone
2. Drag a piece starting near the left edge of the board
3. Sometimes the page also swipes back

App version

0.22.7

Device Info

iPhone 13 mini, iOS 26.3.1
