## Proposed Changes - Based on #1055 - Trigger `onScrollStopped` callback after mouse wheel scroll - Ignore `ScrollableDefaultFlingBehavior`s during mouse scroll to avoid breaking changes - Remove scrolling via `dispatchRawDelta`, `isSmoothScrollingEnabled = false` will just disable animation instead - Add pager test page in mpp demo ## Testing Test: run pager page in mpp demo ## Issues Fixed Fixes JetBrains/compose-multiplatform#3447 Fixes JetBrains/compose-multiplatform#3454
