FileChooser / FileDialog shows hidden files (dot files) in "Recent" even when the "Show hidden files" is deactivated
If you accessed or modified some file (with a text editor, Nautilus, or some other application) in a hidden directory (or a hidden file), the GTK FileChooser will show it in the "Recent" view, even if the "Show Hidden Files" toggle (accessed through the right-click menu in the files list) is turned off.
