 - **The text style panel menus' Duplicate and Delete:** in the Character Styles and Paragraph Styles panel menus, Duplicate highlights the copy, as Create New Style highlights the new style, and Delete leaves no style highlighted, as the Delete button does, so Duplicate, Clear Overrides, Redefine and Style Options are disabled until another style is clicked. A highlighted style that is renamed in Style Options or deleted by a command is no longer highlighted either. The tests `panels::text_styles::tests::panel_menu_duplicate_and_delete_update_the_highlighted_style` and `a_highlighted_style_that_is_no_longer_listed_is_not_highlighted` cover this.
