What is the idea for right-click -> "Copy" and "Select all" (left panel)?

Another “thing” according to the new left panel: Why is it possible to choose “Copy” and “Select All” when doing a right-click on some of the entries in this panel?

I pasted the copied text in an editor and the copied text is just a list of the titles from the left panel.

I would expect that nothing happens after a right-click (no pull-down menu).
