@kumarabhi006 Sorry the long delay.

I tested the behaviour of radio buttons and I can't see or hear any difference in announcements when the same condition, namely `!Objects.equals(newValue, oldValue)`, is used before calling `valueChanged(ptr)`.

I added a panel with three radio buttons to your test case. Initially all the buttons aren't selected. VoiceOver announces when I move to the first radio button. It also announces when I move between radio buttons with left and right arrows. Then when I press the <kbd>Space</kbd> key, the current radio button gets selected and this is announced by VoiceOver: selected, <the caption of the button>. When I move to another button with arrow keys, it doesn't get selected right away when VoiceOver is active, and VoiceOver announces that I moved to another button and that it's not selected. Pressing the <kbd>Space</kbd> key selects the currently active button.

What do you hear when testing such a scenario?
