Clicking an item in a trash bin selects the entire bin

[EbonJaeger]

When clicking an item in a trash bin, GTK thinks that the TrashStore widget should be selected in the top-level GtkListBox, even though the selection mode for both GtkListBoxes is GTK_SELECTION_NONE.

Also, the top trash bin starts selected, which is a long-standing pain-point in GTK3 it seems, causing people to do weird hacky things to make the first item unselected. Maybe there's another container widget that I can use in place of a GtkListBox?
