Strange jump in the scroll of the strip

Does anyone have a similar issue ?

When I scroll the calendar-strip, there seems to be an unwanted render sometimes and jumping back to the begining.

Start by reproducing the calendar-strip scroll behavior using the attached GIF as the reference; the issue names no files, tests, or entry points. Identify the render that causes the strip to jump back to the beginning, then verify that repeated scrolling no longer produces the unwanted jump.
