Highlighting remains visible after changes to Slider and DropdownButton widgets

This issue has been tracked since 2023-03-17.

The highlighting around the slider tick remains visible after the change to the widget completes, same goes for highlighting on dropdown items. The issue was found on a linux desktop app but can be reproduced in dart pad, see code below.

This behavior was implemented based on the Material 3 specification (see #113543)
