Catalog Rule & Selected Categories with level > 3

[SKovbel]

Preconditions

1. M 2.1,4

Steps to reproduce

1. Open form for create new Catalog Rule
2. In Condition Select^ Product Attribute -> Category
3. Open Categories Chooser
4. Select one Category with level = 1, 2 or 3
5. Select one Category with level > 3 (4, 5, ...)
6. Click ok & close Category Chooser
7. Open again Category Chooser and see
   that only categories with level <= 3 are selected
   and category with level > 3 without selection

Expected result

1. All selected priviosly categories must be selected, with level > 3

Actual result

1. Categories with level > 3 are not selected

PS

I used M2.1.,4, but checked 2.3 version and this bug is still present.
Categories with level <= 3 are generated with page with level > 3 with ajax request
For myself I fixed in file Catalog/view/adminhtml/templates/catalog/category/checkboxes/tree.phtml
2. Added selected param to TreeLoader
3. Change Controller from CatalogRule/Controller/Adminhtml/Promo/Widget/CategoriesJson.php
to Catalog/Controller/Adminhtml/Category/Widget/CategoriesJson.php
which can work with selected param
3. After that everything is working
