Object browser, what does an open folder icon mean?

In the object browser, if I expand e.g. the Tables folder, the folder icon shifts to an open folder (a little hard to see in the new dark themed mode, but it is there). When I collapse the Tables folder again, the folder icon still shows an open folder (?). Does the open folder mean, that you already had expanded that folder (after last refresh)?
If I refresh the Tables folder, the icon shifts back to a closed folder.

A little confusing, can someone explain?

I am on a system with 260+ tables (database installed on local computer). Each time I expand the Tables folder, it takes PLD some seconds to display the tables. If an open folder icon means that the tales are already read into in memory why does it take this long to show 260+ table names?
The query itself to list the table names runs in 0.3 seconds.

In version 14, this is done almost instantly, even if the folder has been refreshed.
 
When the information from the folder has been fetched, the icon changes to an opened folder. This is the same as in previous PL/SQL Developer versions.

We'll look into the performance issue.
