Current Behavior

When you start MediaElement the buttons on API level 32 and below do not behave as expected.

Expected Behavior

When you click on Pause/Play it should not just pause but also update the notification icon with current status. It does not. The button does not change if the first pause/play cycle is started from the notification tray. If you start from the player it works fine afterwards.

Steps To Reproduce

1. Open and run sample from repo.
2. Navigate to MediaElement page.
3. Click on pause in notification tray before doing anything on page.
4. Notice that the icon does not update/change.

Anything else?

Issue is caused by a combination of threading and string interpolation. Fix incoming.
