[Notes]:

• The FxR app is closed only after the headset is removed for ~30 seconds.

[Affected Versions]:

[Prerequisites]:

[Steps to reproduce]:

1. Open the newly installed FxR app.
2. Press the vive button on the controller.
3. Select the "Home" option on the pop up.
4. Observe the behavior.

[Expected results]:

• The FxR app is closed and the Vive home screen is displayed.

[Actual results]:

• The FxR app is resumed.

This issue is also reproducible with the latest Firefox Reality 1.4-32171914 (08.06.2019) installed on the Oculus Quest headset and is still present on the HTC Vive Focus Plus as well.
Also, a crash happens every time the app is wrongly resumed.

I will also update the title and description of the issue accordingly.

This should be fixed by #1501 and #1510

I have verified that this issue is no longer reproducible with the latest Firefox Reality 1.4-32182105 (08.07.2019) installed on the Oculus Quest and HTC Vive Focus Plus headset.
Now, the newly installed FxR app can be closed after pressing the vive/oculus button on the controller.
