The current implementation goes beyond the initial scope by introducing unnecessary complexity and implicit requirements.

At this stage, we should focus on a minimal, well-defined component that fulfills its core responsibility and enables fast iteration.
Especially With tight deadlines, simplicity is the key. Additional behaviour can be evaluated and introduced later if there’s a clear need.

[mmitiche]

Additionally, this PR should also integrate the new functional component to atomic-answer-content.

Some more thoughts must be given to where the logic resides. In my opinion it's not in the functional component.
