### Godot version

v4.0.beta.custom_build [bb08997b8]

### System information

Ubuntu 22.10 LTS, GTX1060, Vulkan

### Issue description

If you toggle emulate_touch_from_mouse option in ProjectSettings `InputEventMouseMotion`, `InputEventScreenDrag`, `InputEventScreenTouch` passes through `Panel`, afaik this doesn't happen in **`3.x branch`**

how tree looks:
```
- Node
  - Panel(half screen size, to stop input events)
  - Node(captures unhandled inputs)

```
screen separated into 2 sides, left side is Panel, right is empty space, so if you click on Panel you can't get any output from _unhandled_input on Node.

### Steps to reproduce

1. run attachment
2. click and/or scroll with mouse on left side and right side (check output)
3. go to project settings and toggle `emulate touch from mouse`
4. go to step 2 (check output)
