As of Godot 3.4 is no longer possible to change Button's font color via keyboard focus

Godot version

3.4 rc1

System information

GLES3

Issue description

I had a system where focusing a button with either keyboard or mouse would change the font color to white in order to show the user what they have selected.

As of 3.4 mouse_hover now only reacts to mouse and no longer to keyboard. So grab_focus() or using keyboard no longer triggers a hover effect. This means is no longer possible to change a Button's font color via keyboard focus.

In my game i now have to use a down border like an underline. Notice below my keyboard is on PLAY but my mouse is hovering on SETUP.

I think perhaps we need another Font Color choice perhaps Font Color Focused to change the font color both on keyboard and mouse focus with the hover option as a way to override this if you want mouse to have a different focus color than keyboard. Font Color Hover only works on mouse now.

Steps to reproduce

Just use all empty style for a button. You will no longer be able to tell which button has keyboard focus.

Minimal reproduction project
