Non-standard
      This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The tabStop property of the Element interface returns a Boolean indicating if the element can receive input focus via the tab key. If the specified element is a shadow host tab navigation is delegated to its children.
Syntax
var isTabStop = element.tabStop; element.tabStop = (true|false);
Example
// TBD
