With this change slider is read differently, slider's name is not read
1. Open Ensemble, run Stacked Area Chart sample
2. Click on lowerBound slider, it will be read as:

- Without fix: 55%, lowerBound, slider


- With fix: 55%, slider


Spinner is read same as before.
But with, #1291 , the value of spinner is not read
1. Value is not read when initially spinner gets focus
2. Value is not read when changed

I think, I will have to rework #1291 after this is integrated.
