I have also merged a Mac-specific bug for this issue into this bug. At the time (Oct 17th) I reported that this happened for macOS Sierra version 10.12.6 with VoiceOver 7.0 (477.40.6) 
Google Chrome 64.0.3241.0 (Official Build) canary (64-bit) 
I also reported that this did NOT happen for JAWS, so there might be a regression with that. 

Please let me know if you'd like me to look into the regression further/bisect, etc.
