What you did

Simply enable the DebugPickingPlugin and move cursor over a ViewportNode.

Here's a diff for the viewport_node example that showcases the problem, then run with

cargo run --example viewport_node -F bevy_dev_tools

What went wrong

Hovering over the ViewportNode makes it disappear, as well as toggling the DebugPickingMode also makes the ViewportNode appear/disappear.
