If you zoom an element (tested with arrangements/buttons/labels) and then made it invisible, the same element remains visibile on the screen, but its space is removed from the flow of the page. Watch the video to better understand the problem:
Steps to reproduce the issue
Take a visible element, Zoom it (in or out) and the make it invisible.
Expected Behaviour
The element that has been made invisible should disappear from the screen.
Actual Behaviour
The element remains visible on the screen, but the space previously covered is taken up by the surrounding elements.
If you use Animation_utils/Zoom on an element and then make it invisible, this element should disappear from the screen. But it actually remains visible. Only the space it used to occupy is “deleted”.
In the video above the element that I make invisible by clicking the button is the red horizontal arrangement. As you can see, after it has been made invisible it actually remains visible, and the elements below it are shifted over, going to take their natural position as if the red horizontal arrangement did not exist.
