React version

v20.15.0

Description

When using the NumberInput component with a step prop, the increment behavior is not as expected. Specifically, when the default value is set to "1000" and the step prop is set to 1000, pressing the "+" button should increment the value to "2000". However, the value first increases to "1001" instead. Upon pressing the "+" button again, the value increments to "2001".

Also, the storybook crashes when trying to replicate the same in storybook

Expected Behavior:

• Default value: 1000
• step prop value: 1000
• First press of the "+" button should set the value to 2000.
• Subsequent presses should continue to increment the value by 1000.

Actual Behavior:

• Default value: 1000
• step prop value: 1000
• First press of the "+" button sets the value to 1001.
• Second press sets the value to 2001.
