In the Edit Menu screen, each menu item creates 11 form input elements. In menus with more than 71 menu items, often items after the 71st weren't saved. This was because PHP's runtime configuration `max_input_vars` default value is 1000. Large menus exceed this, so PHP didn't populate the `$_POST` superglobal for the latter menu items. The entire form is now JSON-encoded into a single input which populates `$_POST` manually on form submission. This was attempted previously in [36506] which was reverted in [36507]. Some form fields were not being slurped into the form's JSON representation, and it did not scale for a site with many posts. This approach fixes those problems. Props ocean90, afercia. See #14134.
