[Panel]: Overlay Background not removed when navigating away from the page while overlay is open

Description

Navigating away from overlays does not destroy the overlays properly. The background seems to stay.

Scenario 1: When a page section is rendered inside an overlay and the user clicks the page, the panel correctly navigates to the clicked page but doesn't remove all HTML properties of the overlay from the DOM. The alpha transparent background of the overlay is still visible until the user clicks on it.

Scenario 2: Opening an overlay and then clicking the browser back button.

Expected behavior

Switch to another page by clicking a page in a pagelist rendered inside an overlay or pushing a browser navigation button should remove the complete overlay from the DOM.

To reproduce

Go to the online Kirby Demo.
Go to a page that has a blocks field, like the blog.
Add a block like the image block, that has a configuration overlay.
After adding the block and the overlay for editing the image block is open, press the browser back button.
Now you still see the overlay background.
