This might look like a contrived example in thoses screenshot,
but it happens on small laptop screen often.
This appear to happen only when the show-hint has not enough place to become a dropUp instead of a dropDown.
I'll try to dig the reason myself and try to fix it in a later PR.
unless you beat me at it, or consider a "wontfix".
(I wrote <Tab> in the screenshot, I meant <Ctrl+Space>)
