Presence detection does not appear on top of other windows on Windows

[RebeccaMahany]

The prompts pop up behind all other windows, which will be confusing for end users. We should investigate how to ensure the prompt is brought to the front.

To do presence detection on Windows, we use the window that we create in systray, so maybe the fix lives somewhere in there.

Calling SetForegroundWindow was not immediately useful. Next options to try for troubleshooting:

• Create a new child window from the parent systray window and use that window for presence detection
• Try moving the new child window
• Try sending the new child window to the foreground
