Link Picker - right-hand side elements have no action on click

Log as admin to quickstart and go To the documents where you add a root folder named test
In test add a document of type News named news
Add a folder other_test to test, and a folder yet_another_test to other_test
While in edit mode, scroll down and click on [...] within the element named Link to bring up the Link Picker
In the left-hand side of the link picker click on test to select it
In the right-hand side of the link picker click on another_test to open it

Exp: that it opens and thus shows the contained yet_another_test folder
Act: the entry is highlighted but the container does not open. I have to click on it from the left-hand side view in order to achieve that. I thought that it would work because it's how it behaves if, instead of looking into Documents hierarchy, I look under Assets and/or Images.
