Resizing window and moving button to higher x position than the original window width

[EJTH]

When a button is moved outside of the original window width it stops working (No hover effect, clicks doesnt register)

Here is a sketch to illustrate it:

import controlP5.*;

ControlP5 cp5;
Button button;

void setup() {
  size(400,600);
  surface.setResizable(true);

  cp5 = new ControlP5(this);

  button = cp5.addButton("testbtn")
     .setPosition(width-110,10)
     .setSize(100,20);

}

void testbtn(){
  println("clicked");
}

void draw() {
  button.setPosition(width-110,10);
}

Drag the window to a new size at least 100px wider than the original.

Result:
Button doesnt work

Expected result:
Button should be clickable, but it is not

Calling setGraphics after resize fixes the issue.

cp5.setGraphics(this,0,0);
