Steps to reproduce the problem:
1. Have the Google Maps app installed and pinned to the taskbar.
2. Start up the Chrome web browser and then start Google Maps. 
3. Note how the Chrome web browser's taskbar icon has a white ling under it but Google Maps does not (even when the tab is in focus).

What is the expected behavior?
As with other apps (Gmail, Calendar, Youtube), if an app is running in a web browser it should have a white line under it if running.

What went wrong?
There is no white line under it even when the Google Maps tab is open (whether or not it is in focus or not).

Did this work before? N/A
