### Godot version

v4.2.dev.custom_build [60f3b7967]

### System information

Debian Linux X11 Xfce

### Issue description

Physics Picking within a `SubViewport` happens with `InputEventMouse` even when mouse events are disabled via `SubViewportContainer.mouse_filter = Control.MOUSE_FILTER_IGNORE`

The problem is that passive hovering still happens in the `SubViewport` with `SubViewportContainer.mouse_filter = Control.MOUSE_FILTER_IGNORE`.

I assume that it is a regression from #78017.

This was initially reported as a side-effect in #79271, which got closed, because the main issue was resolved.



### Steps to reproduce

1. Load and run MRP
2. move mouse over Icon

I would expect, that the `Area2D` receives no `InputEventMouse`, however it gets `_input_event` and also mouse-entered and mouse-exited signals.
