Pivot accessibility issues

[betrue-final-final]

Environment: IE11 and JAWS 18
Are you willing to submit a PR to fix? No. I need help
Requested priority: High

1. Titles are not announced for the pivots
   Expect: When a pivot gets focus, announce the name

2. Doesn't announce when a pivot is selected
   Expect: Should say " selected"

#1 does not repro in Narrator, but #2 does.
