Issue

It was possible to save a category with stale data from a duplicate browser tab, creating a circular dependency.

Steps to reproduce:

  1. Create a category structure: A > B > C.

  2. In the Admin panel, go to Catalog > Categories.

  3. In the category tree, select category C to open its edit form in Tab 1.

  4. Duplicate the browser tab to open Tab 2 with the same category C edit form.

  5. In Tab 1:

    1. Drag category C under A so C becomes a child of A.
    2. Drag category B under C so B becomes a child of C.
    3. Wait until both drag-and-drop operations finish and the category tree updates.

  6. In Tab 2 (still showing the old hierarchy):

    1. Make any change, for example, edit the description.
    2. Click Save.

Expected results:

The system should validate and prevent circular parent-child relationships from being saved.

Actual results:

A circular parent-child dependency is created between categories (category B has parent C, and category C has parent B), causing infinite recursion in category hierarchy traversal.
