Cycling dowpdowns with Tab wont allow to search them

[ghost]

I have a couple of searchable dropdowns on a page, and when I use tab to cycle, they become focused, but the searchable input is not. I have to click to open and them make the search.
Is it possible to expose an onFocus callback?
Or if the dropdown is focused and searchable... It should allow to search on key down?

This fixes the focus and open, but once focused, it won't cycle between different dropdowns.
Only if I select a value.

Hit escape to loose focus of open one and continue with tabs.
