Fixes #225759

Changes

• Modified the _isAlmostInt method in the MouseWheelClassifier class to increase the margin of error.
• Changed the threshold from 0.01 to 0.01 + Number.EPSILON * 100 (approximately 0.010000000000022205).

Reason for Change

To account for floating-point errors in certain zoom level calculations.

Previous Behavior

• For most zoom levels deltaY = 0.996 ~ 1 and _isAlmostInt correctly returned true.
• At zoom level 1, with deltaY of 0.9899999999999999, _isAlmostInt incorrectly returned false.

New Behavior

• _isAlmostInt now correctly returns true for zoom level 1 cases, as intended.

Testing

1. Set zoom level to 1.
2. Verify that _isAlmostInt returns true for deltaY values very close to 1.
3. Check that the method still behaves correctly for other zoom levels.

Additional Notes

This change helps maintain consistent behavior across different zoom levels, addressing edge cases where floating-point precision was causing unexpected results.
