If a KeyNav container is the last tab-navigable element on the page, then shift-tabbing from the browser address bar will end up on the last tab-navigable element in the KeyNav container, rather than the first one or the previously focused element.
Partly this is due to KeyNav#_tabKeyPressed not being set in this case, and partly due to KeyNav containing a bunch of tabindex=0 nodes rather than tabindex=-1. For tables created with deliteful/List, that statement applies to both the tab-navigable cells as well as tab-navigable components within the cells.
