KeyPressFcn and WindowKeyPressFcn not working

I have a GUI (using the old figure, not uifigure). The figure has a KeyPressFcn to do some action.
So I have a pushbutton, and after clicking it I want to hide the button, so its callback turns off its visibility ('Visible', 'off').
When that happens, the KeyPressFcn (or WindowKeyPressFcn I also tried it) if the figure stops working. No matter what I do, I can't recover the focus.
So this is what I tried, and nothing worked, even with everything combined:
set(figHandle, 'CurrentObject', figHandle)
set(figHandle, 'CurrentObject', pushbuttonHandle)
figure(figHandle)
gco(figHandle)
gcf(figHandle)
figHandle.Visible = 'off'
figHandle.Visible = 'on'
drawnow
NOTHING WORKS.
Only way to make it work again is clicking the figure. But thats exactly what I DONT want to do. I must not click the figure after clicking the pushbutton, at least before the desired keypress.
However, if I enter debubg mode using breakpoints, then this works:
set(figHandle, 'CurrentObject', figHandle)
figure(figHandle)
But it does not work if not in debug mode. I don't understand this behaviour. I know removing visbility to objects have some strange side effects. But it should never remove permanently focus from a figure.
Why does it work in debugging mode, but not in normal mode?

Rather than setting the pushbutton invisible in its callback, try setting its position to something outside the figure, e.g., [-10 -10 1 1], and see if that changes anything.
