Language dropdown/select doesn't close when clicking somewhere else

When you click the language selector and you try to close it by clicking outside the element, it doesn't close and you must click `Language` again to collapse it. The expected behavior should be that if you click `Language` and then you click outside of the dropdown, it should hide.

Thanks for this awesome work!

Start at the language selector entry point and reproduce the issue by opening the dropdown, then clicking outside it. Trace the outside-click behavior and verify that the dropdown hides when the click occurs elsewhere, while still closing through the Language control.
