As the "onunmatch" is triggered AFTER the element is removed
from the DOM it never finds the `closest('div')` when switching
screens. E.g. when using GridField edit
So when you go from the GridField edit screen back to the page
you end up with the page loaded but the spinner doesn't disappear
Other option would be to do `$('body').find('.cms-content-loading-overlay,.cms-content-loading-spinner').remove()`
but this is probably a bit drastic

Client-side validation is not essential (we can only rely on server-side validation being enforced).
