Research direction
Reproduce the issue in the M3 Catalog minimal sample on Android API 34 with Material Library 1.13.0-alpha08, using a CollapsingToolbarLayout and a scrollable view. Start by observing the title during the start of a fling; done means the title no longer shifts or shakes at that point.
