Create listener for changes in position of a figure window

I have been trying to use addlistener() to make it so that when one figure window is moved, another figure window shifts position by the same amount, so that their relative positions are always the same:

h1=figure(1);
plot(1:5);
h2=figure(2);
imshow(imread('cameraman.tif'));

addlistener(h2,'Position','PostSet', @(s,e)callback(s,e,h1))


function callback(h2,~,h1)

 h1.Position(1:2)=h2.Position(1:2)-[500,0];

end

However, this results in,

Error using matlab.ui.Figure/addlistener
While adding a PostSet listener, property 'Position' in class 'matlab.ui.Figure' is not defined to be
SetObservable.

Error in test (line 8)
addlistener(h2,'Position','PostSet', @(s,e)callback(s,e,h1))

Does anyone know of a workaround that will allow me to do this?
