NestedScrollView scrolls back to top when using MacOS trackpad #116486
Description
Steps to Reproduce
- run example 1 of NestedScrollView
- keep scrolling down before scroll ended, then you can see the strange behavior in video
Works normal on web and mobile(iOS), strange in macOS. It seems flutter calculates offset from top again when previous scroll is still scrolling.
Actual results:
