Unexpected zoom triggered by two-finger vertical gesture on MacBook trackpad #89
Description
Description
When using a two-finger gesture on a MacBook trackpad to move the graph vertically (up or down), the graph unexpectedly scales in addition to moving—but only when the browser page is zoomed out (e.g., at 75%).
This issue does not occur when moving the graph horizontally; horizontal gestures work as expected without triggering zoom.
Steps to Reproduce
Open the graph in a browser.
- Zoom out the entire page to 75% (using Cmd + - or browser zoom controls).
- Use a two-finger vertical gesture on the MacBook trackpad to pan the graph.
- Observe that the graph not only moves but also unintentionally zooms.
Expected Behavior
The graph should only move vertically without any change in scale or zoom level.
