Panel not collapsing when using push

[Juchar]

Hello,

I am in a situation where I need to show a spinner in the UI. By consequence I manually push that change to the UI by doing:

UI.getCurrent().push();

The cause I need to do this is that before I navigate to a view I want to show a spinner as some views could contain heavy computations before they are finished to show.

Unfortunately, if i collapse the SliderPanel and show the spinner using push, the SilderPanel gets visible again after the view is visible.

I attached a minimum sample: push-example.zip
