It's so weird (I don't know if you've left this thread or not). I'm working on a virtualbox linux at home and chrome doesn't work on drop-down menus. I only discovered this because I was trying out a browser called vivaldi (which I really like but it has chrome dna) and it didn't work there. So I tried chrome and- indeed- it doesn't work in chrome either. Works fine in firefox.
Upon googling, I discovered that drop-down menus have been an issue in chrome (even not using vbox). I'm using zurb foundation for the menu js/css, fwiw.
(Also, I think a lot of people discount how good Edge's Dev Tools have gotten. There too my corporate mandated environment is mostly stuck with Windows 7 and an intentionally broken IE 11 due to Oracle and using their terrible software internally.)
