## Problem/motivation Follow-up to: #3586258+s Pull item 7.3 from: #3586299+s _**Verify the issue problem and solution before proceeding.**_ ### Avoid functional-test dual-container traps **File:** - `tests/src/Functional/AiContextAdminSettingsTest.php` **Problem:** At least one functional test submits a form directly through the test container's `form_builder`. Functional tests run separate test and web-server containers, so direct form builder submission can miss browser/runtime behavior. **Recommended fix:** - Use `$this->drupalGet()` and browser-level `$this->submitForm()` when testing user-facing forms. - If direct form API testing is intentional, move that coverage to a Kernel test or document why direct submission is appropriate. ## AI usage - [x] AI assisted issue
