{# Inline-edit popover body (static/js/list.js `initInlineEdit`): the control slot starts in a loading state (spinner) and is swapped with the server-rendered form fragment (`inline-edit/field.html`) once fetched. The save button is the form's submit button so Enter in a single-line input saves; it stays disabled until the fragment has loaded. The cancel button is wrapped in `inline_edit_cancel_button` so a theme can restyle it (e.g. give it a visible Bootstrap button variant) without duplicating the rest of this fragment. The `.inline-edit-cancel` class is required by list.js. #}
