REPL autocomplete doesn't work with specific `using` statement

When I import a name via using the autocomplete doesn’t work while it does work when I import the same name.

using Pkg: activate

activate is not completed upon pressing of the tab key.


import Pkg: activate

it is completed.
I find this strange as using Pkg makes autocomplete work on all exported names of Pkg, although their not imported but only used.
If I don’t want to import the names, a workaround would be
const activate = Pkg.activate but then I cannot decide late to import it.

Is there some reason behind this behaviour?

This is a bug in tab completion.
