Button isn't inserted to task view in Asana's new Timeline view

Environment details

• Operation system: MacOS Sierra 10.12.6, Chrome Version 65.0.3325.162 (Official Build) (64-bit)
• Extension version: 1.10.3

Expected behavior

Insert "Start Timer" button into every SingleTaskPane element on Asana.

Actual behavior

In the new Timeline view in Asana (currently beta) it's possible to open a SingleTaskPane to view task details as in Asana's List view, but the button isn't inserted.

Steps to reproduce the behavior

In Asana on an account with Timeline view, go to a project, click the Timeline tab to open or populate Timeline view, and click on a task.

Additional details

I realize that the fact that Timeline view is beta makes this low-priority, but I thought it'd be better to open a ticket earlier rather than later.

Possibly the same report, waiting for screenshot to confirm whether it is specifically Timeline the user is referring to - case/678714
