Mouse Press blocked by Texture below

[Grosskopf]

Godot version:
3.2.3

OS/device including version:
Intel Processor on Opensuse Linux, GLES3

Issue description:
I had a button I wanted in front of my background Textures, so I parented it to a Node2D and increased the Node2D's Z value so i could see the Button. I was not able to Press the button until I set the mouse_filter of the Texture in the background to Ignore it.

Steps to reproduce:

create a scene with:

• control
  • Node2D with Z value 1
    • Button
  • Texture Rect covering the Button's background, mouse_filter set to anything but ignore

see that you cannot press the button even though it is in front of the texture

Minimal reproduction project:
