i can't reproduce problem like description
Tested with my own local instance (latest code 2.4-develop) + Sample product with luma default + same preconditions as your describe
(Category tops)
(Details of product Chaz Kangeroo Hoodie)
Empty category page (no products assigned)

[chaikivskyi]

@mrtuvn I can't be sure that you understand the issue by your screenshots.
I can explain the issue on the code level.
7f6e9a8 - it is a related commit to this issue which exists in the 2.4-develop branch, but I think the author missed some details.
https://github.com/magento/magento2/blob/2.4-develop/app/code/Magento/Catalog/Controller/Product/View.php#L198 - in my opinion, we should setCategory to a product like in the https://github.com/magento/magento2/blob/2.4-develop/app/code/Magento/Catalog/Helper/Product.php#L460. Because the function getDesignSettings do not return the right value from category when the product does not contain a category.

[mrtuvn]

So i think you can update more details in preconditions for QA/QC team can easier reproduce your scenario
From my experience products in category list page already set category_id for each products listed in block. Reference this class app/code/Magento/Catalog/Block/Product/ListProduct.php
Feel free to create pull request if you want to cover missing case

[chaikivskyi]

@mrtuvn Controller Product/View.php does not work on the product listing. It is a product page. Please, do next steps to reproduce the issue:

1. Create a new theme
2. Apply a theme for only one category and enable the setting Apply Design to Products https://imgur.com/zqHGfAG
3. Create new layout rules for the catalog_product_view handle in the new theme. These rules will not be applied on the product page.

[engcom-November]

Verified the issue on Magento 2.4-develop branch and the issue is reproducible:
Default theme - Luma
Configured Magento Blank theme for the category on the category edit page in admin panel (Catalog -> Categories -> Add Root Category -> Design - Enable " Apply Design to Products" )
Navigate to Catalog - Products -> Add new product / Edit Product -> Assign the newly created Category and remove other categories if any.
Front End - Go to the product page - Default Theme is getting applied.
Actual Result: Default theme - Luma is applied

Expected behavior: - Magento theme should be applied.

Note: This issue is resolved only if Admin -> Catalog -. Products -> Edit Product -> Design section is also modified. (Magento Blank theme is applied in Design section)

cc: @tsviklinskyi Can you check comment #33428 (comment)
Seem we miss specific case customer go directly to product without visit category page. In this case product may not contain category information so design will not apply
