Hi @kumarabhi006 
I ran this test when trying to backport it to 21/17.
I get unexpected readings when I use the up/down arrows.
* Sometimes it says the right percentages
* Sometimes it says correct numbers
* Sometimes it says arbitrary numbers (it says "11" when I step from 14 to 15).
I tried it with my backport for 21, but also with 24 and head. They all show similar behavior.
But I'm not experienced with using VoiceOver, did I use it wrongly?
