 * A horizontal tab keeps its label whole, and when the tabs are wider than the
 * list the list scrolls. The shared tab rules (XWUINavTabs.css) give every
 * .xwui-tab `min-width: 0; width: 100%`, written for a tab inside a
 * non-shrinking .xwui-tab-item; XWUITabs puts its tabs straight in the list,
 * so they shrank and their labels ended in an ellipsis ("Comp…") as soon as
 * the row was narrower than the tabs (five tabs on a 390 pixel phone).
 * Full-width tabs still share the row, but not below their label.
