VO+Tab, the VoiceOver passthrough command, or "ignore next keypress" command, appears to be non-functional in Mac OS 12.2.1.
To reproduce, open any app or window. Press VO+Tab. Then try to navigate with VO+Right or Left arrow. The expected behavior is that the navigation command should be ignored. However, on current Mac OS, the navigation command is not ignored.
I first encountered this with invert colors, and mentioned it in this forum topic. However, I've now discovered this is not specific to invert colors and seems to be a problem with the passthrough command in general.
I'm on a 2019 Mac Mini. Resetting the NVRAM has no effect. Please let me know if anyone else can confirm this issue. Thanks.
