Bug description

There's an inconsistency in the zoom behavior when using zoom.in() with different parameter types:

1. When passing an Event object, zooming works correctly - it zooms in while maintaining focus on the cursor position (expected behavior)

2. When passing a number (zoom ratio), the zoom centers on the last clicked position rather than the center of the slider (unexpected behavior)

Reproduction Steps:

1. Initialize Swiper with zoom module
2. Click anywhere on the slider
3. Call twice swiper.zoom.in(ratio)
4. Observe zoom centers on last clicked position instead of slider center

Expected Behavior

When providing a number parameter to zoom.in(), the zoom operation should:

1. Default to the center of the slider container
2. Maintain consistent behavior regardless of previous interactions
3. Match the behavior seen in other zoom implementations where programmatic zoom typically centers

Actual Behavior

• swiper.zoom.in(event) → Zooms to cursor position (correct)
• swiper.zoom.in(ratio) → Zooms to last clicked position on slider (incorrect)
