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

[rcardona-eb]

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!
