Control Node Navigation impossible using Joystick

Godot version

3.4.stable.official [206ba70]

System information

Windows 10 Pro, GLES3, AMD Ryzen 7 2700X, NVIDIA GeForce GTX 1660 SUPER (Driver ver. 27.21.14.5671)

Issue description

When using the Joystick on a gamepad, the game registers a change in focus every frame, which makes it impossible to navigate Menus. I submitted a similar issue a year ago here, but back then it only applied to OptionButton Nodes. This time (since I changed to 3.4) all Control Nodes seem to be affected.

Steps to reproduce

Create a scene with a couple of Button Nodes.
Map ui_left, ui_right, ui_up, ui_down to your the corresponding Joystick axis of your gamepad in Project Settings.
Try to navigate the Buttons, using the Joystick (not the D-Pad!)
You will notice that the cursor moves erratically, because focus changes rapidly.
