SteamVR: Quitting a title using the 'Exit Game' button from the SteamVR Overlay will return the user to SteamVR Home environment while the title is still running in the background.

[KWS-Compat]

When the user launches a VR title while SteamVR is not running, closing the title via the 'Exit Game' button (see attachment 1) will return the user to SteamVR Home environment on the HMD. However, the affected title is observed to still running on the Desktop screen. The affected titles also cause SteamVR to throw an 422 error code (compositor is not available) on the HTC Vive Pro (see attachment 2).

Prerequisite:

1. Ensure that SteamVR is not running.

Repro Steps:

1. Launch an affected VR title.
2. Wait until the title is fully loaded, open SteamVR Overlay.
3. Select on the currently running title thumbnail.
4. Select 'Exit Game' button. Observe that the user is returned to SteamVR Home in the HMD, and the title is still running with its Window still present on the Desktop.

Notes:

• Some of the affected titles also cause SteamVR to throw a 422 error message when using the HTC Vive Pro (related to Github #103).

The issue was observed to no longer occur as of SteamVR Beta Build 1.3.17.

After launching a VR title prior to SteamVR, using the 'Exit Game' button on the SteamVR Overlay will return the user to SteamVR Home and the VR title gracefully close. Occasionally, the user will see a 422 error message pops up only on the HTC Vive Pro, however it does not occur at all on the HTC Vive. The user is still able to interact with SteamVR normally without any issue despite the error message.
