Clearing "Filter groups" also clears group selection #6308
Description
In JabRef 5.0, if one enters text in "Filter groups", selects a group and clears "Filter groups", the group is unselected. All entries are shown, although sometimes some group is highlighted in the group interface, as if it was selected (and sometimes "All entries" ends up being highlighted). The expected behaviour would be that the selection would be kept, preferably the group interface would also be scrolled so that the selected group would be visible.
