Magento 2.4.8-p3 : Cannot switch a dropdown attribute to is_filterable_in_search = 1 (if is_searchable = 0 ?)

[rbayet]

On a Magento 2.4.8-p3 Enterprise with the sample data, it seems it is not possible anymore to switch a dropdown attribute (activity, style_bags) to being is_filterable_in_search = 1.

installed with

• composer require --ignore-platform-reqs hyva-themes/magento2-smile-elasticsuite ~1.2
• composer require --ignore-platform-reqs hyva-themes/magento2-default-theme

Steps to reproduce

1. Install a fresh Magento 2.4.8-p3 Enterprise
2. Install the sample data
3. Install the Hÿva modules
4. Reindex everything
5. In Magento admin, edit the "activity" attribute which is only filterable in catalog (Use in Layered Navigation = Yes), switch "Use in Search Results Layered Navigation" from No to Yes, save the form

Expected result

1. After the page refreshes, "Use in Search Results Layered Navigation" is set to "Yes"

Actual result

1. "Use in Search Results Layered Navigation" is set to "No"
2. If you switch the attribute from "Use in Search" = No to "Use in Search" = Yes AND "Use in Search Results Layered Navigation" back to Yes and you save
3. THEN after the page refreshes, "Use in Search Results Layered Navigation" = Yes as expected

Additional behavior that could confirm that something enforces somewhere the rule "is_filterable_in_search cannot be set to 1 if is_searchable = 0" :

• execute request update catalog_eav_attribute set is_searchable = 0, is_filterable_in_search = 1 where attribute_id IN (select attribute_id from eav_attribute where attribute_code = 'activity'); which set the activity attribute to non-searchable but filterable in search
• edit the attribute in Admin: the attribute is correctly shown as "Use in Search" = No and "Use in Search Results Layered Navigation" = Yes
• save the attribute
• after the page refreshes, the attribute is now in "Use in Search Results Layered Navigation" = No

It could indeed indicate something is now done on the server-side now.

We initially dismantled the rendering mechanism (dependency on fields) here : 67666a7

It looks it's not sufficient anymore :/
