zoomIn(step) overshoots defined scale when smooth: true is enabled

[madsone]

Describe the bug
When using zoomIn(0.25) with smooth: true enabled in TransformWrapper, the resulting scale overshoots the expected increment. For example, instead of increasing by exactly 0.25, the scale jumps by approximately 0.28.

To Reproduce
Steps to reproduce the behavior:

1. Wrap content in
2. Call zoomIn(0.25) from a button or event
3. Observe the resulting scale in onTransformed or useTransformEffect
4. See that the scale is not exactly +0.25 from the previous value

Expected behavior
The scale should increase by exactly the defined step (e.g. +0.25) when zoomIn(step) is called, regardless of smoothing.
