Some of us use a password manager to maintain our credentials, and it can be rather frustrating to enter them when the password prompt disappears the moment the VSCode window loses focus. I have to go copy the password, and in the meantime, the prompt is now gone, so I now have however many seconds until my password manager clears the clipboard to re-initiate the connection request. It's a relatively small annoyance, but it's constant, and – well, it's annoying enough for me to find where to post requests and post one.
I've used other plugins that keep the password prompt up when focus is lost, so I know it's possible. Please stop if from disappearing!
