Window jumping when pointing to the "Dismantle" button

When a window is docked to the bottom of the screen and you point with the mouse cursor on the "Dismantle" button the window jumps up and down, because the ressources that you will get from dismantling are shown (window gets higher). But this results in the mouse cursor is no longer above the "Dismantle" button and the ressources are no longer shown (window gets smaller again) => infinite loop.

You have to move the window away from the bottom of the screen to hit the button.

I could think of two solutions for that:
- automatically moving the mouse cursor above the "Dismantle" button again after the window was expanded (I would prefer this solution).
- keep the window always in the same size all the time (leaving enough space to display the ressources from dismantling if needed).

But maybe somebody else has an even better solution for that.
