In T368422, an initial version was implemented to support basic topic selection in order to customize translation suggestions. The "Adjust suggestions view" provides a list of topics for users to select. This is intended to work similar to a [Codex dialog component](https://doc.wikimedia.org/codex/latest/components/demos/dialog.html). However, currently it uses a non-standard transition: it appears flying from below the viewport and goes away flying up (not going to the same place where it came from):

Following the [Codex dialog component](https://doc.wikimedia.org/codex/latest/components/demos/dialog.html) and the current Codex [support for transitions](https://doc.wikimedia.org/codex/latest/design-tokens/transition.html), it seems that the standard is for elements to fade in/out.
___
It is not clear what motivated the use of the current transition. If there is a reason for this to show form below the viewport, we can consider keeping it but adjusting the way the elements disappear by flying back to the bottom too.
==Derived Requirement==
Ensure that the "Adjust suggestions view" in the basic topic selection uses standard transitions for appearing and disappearing. These transitions should follow the Codex dialog component's fade-in and fade-out behavior. If a reason exists for using the current transition (flying from below the viewport), adjust it to ensure consistency by making the element disappear by flying back to the bottom.
====Test Steps
__Test Case 1: Verify Standard Fade-in and Fade-out Transition for "Adjust Suggestions View"__
1. Navigate to the translation suggestions interface.
2. Open the "Adjust suggestions view" by selecting the corresponding option.
3. ✅ **AC1:** Confirm that the "Adjust suggestions view" fades into the viewport smoothly, following Codex dialog component standards.
