winssh-pageant does not work after last update

We've introduced functionality to suppress prompts for SSH requests that come from background apps, to avoid unexpected prompts showing up (e.g. IDE performing a background Git fetch while you're watching a movie). You can still manually bring up these prompts from the 1Password system tray icon.

That said, there might be a false positive in the background app detection for winssh-pageant. We'll try to reproduce this so we can fix it.
