Keep archives selected, not extracted folders
In previous versions (e.g. nautilus in Ubuntu 16.04 and before), selecting archives and extracting them with the right-click menu left the selection intact. Now, the newly created folders are selected.
The archives should be still selected or at least it should be configurable if either the archives or the extracted content is going to be selected.
Benefits of the solution
It does not break with old user expectations and allows the user to delete the archives immediately without re-selecting them (which can be a pain if they cannot be selected at once).
Restoring the old behavior might confuse new users.
