ListItem focus state not applied when previous focus was outside of iframe

[bdares]

Problem description

I have a DOM that looks like this:

div#outside
div#inside
  -iframe
    - List
      - ListItem
      - ListItem

When focus is on div#outside and I hit {Tab} then the first ListItem gains focus. However, the focus state visual indicator is not applied.

Steps to reproduce

Make DOM structure as above. Focus on an element outside of the iframe, then tab to focus the first ListItem within the iframe. Observe that the first ListItem focus state is not applied.

We have been porting the component on the v1-beta branch. We reimplemented it from the ground-up. While we haven't tested it, I think that the issue is most likely fixed on that branch. Hence, I'm closing it.
Still, we will accept PR fixes until v1-beta takes over the master branch.
