Cockpit widget was glitching after refreshing the page

Oh, we don't need to refresh the page, maybe just hide the Cockpit page for a while and show it again.

Start with the Cockpit page and widget entry points, then reproduce the behavior shown in the attached recording by hiding and showing the page. Trace what changes during that transition and confirm the widget no longer glitches afterward; the issue provides no file or test names, so the relevant code must first be located.
