### Issue description

No matter what I do Project Camera Override can never detect a game instance.

Of relevance: I can see remote nodes. I can see the output in the console. I can see the output in my IDE of choice (Rider). I can toggle debug mode.

It's just the camera that is unable to detect the game instance.

### Steps to reproduce

This happens everywhere, including on a brand new projects where the only nodes are a 2d camera and the Godot svg icon for testing. This also seems to happen when not using Rider as a third party editor.

### Minimal reproduction project

}
void CanvasItemEditor::_draw_percentage_at_position(real_t p_value, Point2 p_position, Side p_side) {
	String str = TS->format_number(vformat("%.1f ", p_value * 100.0)) + TS->percent_sign();
	if (p_value != 0) {
