Adding Stephen as the owner of the test - do any of the CLs in that range seem like they could cause this test to fail?

Revert "Reland "Composite ScrollTimeline scrollSource when appropriate.""

This reverts commit 48f503a88abc242e8aba16ac1f6ec7eac6d104c3.

Reason for revert: Failing the Linux Trusty Leak bot

Original change's description:
> Reland "Composite ScrollTimeline scrollSource when appropriate."
> 
> This is a reland of ddd9f0eec9abf574e6995f9034fa519e069fa1fd

> Original change's description:
> > Composite ScrollTimeline scrollSource when appropriate.

> > This CL makes being the scrollSource of an active (i.e. the scrollSource is
> > scrollable) and attached (i.e. it is being used by at least one WorkletAnimation
> > as a timeline) ScrollTimeline a compositing reason. It does not change the
> > requirement that the scrollSource must be composited for the WorkletAnimation to
> > be sent to the compositor, nor does it change the case where a scrollSource stops
> > being composited whilst a WorkletAnimation is running. Those will be addressed in
