Description

Page Settings can't be saved, especially background styles when we edit page settings only, without editing any existing elements on editor.

Steps to reproduce

Case 1 (OK, page settings can be saved)

1. Edit existing elementor page
2. Edit background styles on page settings
3. Edit any existing element on editor
4. Click save button

Case 2 (NOT OK, page settings can not be saved)

1. Edit existing elementor page
2. Edit background styles on page settings
   (Do not edit any existing element on editor)
3. Click save button

Note

I can see that when you edit any existing element, the save editor button changes to "green".

But when you edit page settings ONLY, the save editor button doesn't change to "green".
