"Timeline Switcher" is not switching between the created timelines(eg. Cube Timeline and Point Light Timelines) when the focus on GameObject in the hierarchy. Refer to the attached video.

Steps to repro:
1. Create a new project
2. Add a Point Light and Cube in the Scene
3. Window > Sequencing > Timeline
4. Focus on the Cube in the Hierarchy and create CubeTimeline
5. Focus on the Point Light in the Hierarchy and create Point LightTimeline
6. Focus on the Cube in the Hierarchy
7. Click on "Timeline Switcher" and Switch between to Cube and Point Light Timelines

Actual Result:
Unable to Switch between to Cube and Point Light Timelines when focus on the GameObject in the Hierarchy

Expected Result:
Able to switch between Timelines using the Timeline Switcher

Reproducible in: 2020.1.0a2, 2019.3.0b1, 2019.2.1f1, 2019.1.0f2, 2018.3.0f2

Package reproducible version: 1.2.2, 1.2.1
