My app has an NSpopover and its contentView's hierarchy is as follow, but when voice over is on, it will only announce "You are on a cell".
I want VoiceOVer read keyboard navigation hints ( like this picture).:
NStableView inside a NSpopover doesn't read VoiceOver keyboard navigation hints
Setting the NSPopover's window's accessibilityRole to windows will make VO read the hints, but not work on Catalina and versions before
