Rating is not accessible via tab

[Theartbug]

Cannot use keyboard tab to access each individual rating input.

Current behavior: pressing tab skips over the entire component.

Desired behavior: tab would jump into the first rating and tab across them, selecting them when enter is pressed.

Looked into code, making it "tababble" isn't that hard. Though several other problems emerge. Apparently value change is bound to click and I can not see painless way to solve this issue without rewriting most of value handling mechanism.

// do not update internal state based on input value if prop passed
if (value != null) { return; }
