In Livetable, the delete action is icon is colored in red (more precisely, the $theme.notificationErrorColor color, see https://github.com/xwiki/xwiki-platform/blob/1d9d01326a83c9816d9a8cfe5697dc147b40f877/xwiki-platform-core/xwiki-platform-web/xwiki-platform-web-war/src/main/webapp/resources/js/xwiki/table/livetable.css#L221)

This is not the case for Live Data. Consequently, all the Livetables migrated to Live Data with a delete action have the wrong color for the delete action.
