Removed the duplicate style properties for the list widget

Editor assessment

The subject is clear, duplicate style properties removed from the list widget, and refactor is the correct type for the deduplication. The body, though, only restates the headline and then notes that list_spec Cypress failures were fixed, which hints the refactor had behavioral stakes that go unexplored. Why the duplicates existed and what risk they carried is never said. No scope is needed because the subject names the widget, past tense dominates, and the issue reference anchors the change. Mechanically sound, motivation-free.
