Identify and close feature test gaps for work item list
### Work items list
This epics targets to cover sanity checks related related to work item list.
### Feature flags to consider
1. Enable the work items experience for the issues on a project - `work_item_view_for_issues`
2. Enable the new consolidated `Work Items` menu instead of issues - `work_item_planning_view`
3. Enable the drawer on projects - `issues_list_drawer`
4. Enable the drawer on groups - `epics_list_drawer`

### Feature spec guideline for work items
* Search for existing spec files by name like `user_<action>_work_items.rb` and reuse if available.
* If no existing file, create one under `ee/spec/features/work_items/` for EE or `spec/features/work_items/` for FOSS/shared.
* Do not create separate spec files based on work item types like task or objective. If absolutely required, create under a type-specific folder (e.g., `epics/`) and add a note that it is temporary.
* If the feature is behind a feature flag, test both enabled and disabled states.
* Use simple test data, especially when dealing with dates or time-sensitive fields.
* Avoid combining multiple attribute states or scenarios in a single test case for less flaky test. Instead add deterministic setups.
* If complex setup is unavoidable, add query limits using `allow(Gitlab::QueryLimiting::Transaction).to receive(:threshold).and_return(175)` if needed.
* Follow GitLab testing guidelines to keep feature specs lightweight and focused.
