Bug ID: 27965
Summary: [Shadow]: Shadow host with tabindex=-1, all descendent
tree should be ignored for tab navigation

In the current Shadow DOM spec, basically focusable nodes in a shadow tree are
inserted after their shadow host in the tab navigation order.
This means that when shadow host has "tabindex=-1", the host itself is skipped
in the order, but right after the host the descendant nodes in its shadow tree
will be visited.
This is probably not the behavior that a component author or user would expect.
