Container content changes based on the current position of the mouse
How to reproduce: go to an area where there are several containers (e.g. the basement jail Cell in "Gnisis, Arvs-Drelen") and open a crate. Move the mouse to point to anther crate and press the activation key (e.g. space). The contents of another crate is shown.
Vanilla behaviour: the open dialogue is closed when the activation key is pressed while pointing to another container.
