Issue: Android scroll glow effect does not stay at set paintOffset when scrolling in opposite direction
Labels: platform-android,framework,f: material design,f: scrolling,has reproducible steps,P2,found in release: 2.8,found in release: 2.9,team-android,triaged-android

## Steps to Reproduce

1. Execute `flutter run` on the code sample (Android)
2. Enable slow animations so that the scroll glow stays longer.
3. Scroll to the end of the list so that the scroll glow effect appears.
4. Immediately after slowly scroll back up again.

**Expected results:** 
The glow effect should stay at the (initial) `paintOffset` position above the bottom bar.

**Actual results:**
The glow effect scrolls with the content of the `ListView` and then pins at the end of the view port.
