Radio button issues: tabbing inconsistency across browsers

[Skaiir]

Describe the Bug

There are two issues:

• When we tab across radio buttons not in firefox, the focus jumps and skips consecutive radio buttons
• When we tab across radio buttons in firefox, the focus is handled for every radio element

Steps to Reproduce

1. start the viewer
2. open it in firefox
3. tab across a radio component
4. each radio element gets selected
5. put two radio components in the viewer test file after one-another
6. start the viewer
7. open in in chrome
8. tab across them
9. the second (and all following) radio buttons gets skipped entirely

I think this is probably due to the fact that radio components aren't named in either case which is why I made this a single issue.

Expected Behavior

(4) => radio elements should not be tabbed through
(9) => only a single radio group should be tabbed over
