Hold down Button times out

[usbalbin]

Hi!

I want to run a piece of code every tick a button is kept down. After some searching, i found Button::is_pointer_button_down_on. This seems to be the right thing from what I can tell. However for some reason it is as if the "hold down" times out. After about 1 second or 48ticks the button is visibly released and Hi! is no longer shown even though I am still holding down the button. If I move the mouse (still inside the button) while holding down the left mouse button, it is released immediately.

if ui.button("BTN").is_pointer_button_down_on() {
    self.i = self.i.wrapping_add(1);
    ui.label("HI!");
}
ui.label(format!("Count {}", self.i));

Background

I am communicating with some hardware with some actuators. For some sort of safety I would prefer if the actuator only moved while the button is held down. So every tick the button is held down I send a "keep running" command. Once the button is release the hardware times out and stops the actuator.
