What:

Exclude descendants of hidden elements.
Replaces #556

Why:

Browser does not include hidden parts of the DOM tree in tab order.

How:

Run window.getComputedStyle() for every ancestor element.
If one is hidden, exclude the element from tab order.

Checklist:

  • N/A Documentation
  • Tests
  • N/A Typings
  • Ready to be merged

Hidden elements should be excluded from tab order.
Hidden attribute can be overwritten by stylesheets.

There is a bug in jsdom that has to be resolved first.
See jsdom/jsdom#3111
