Hi, It's me again, somebody in the gnome bug report (see [1]) found the commit that caused this behaviour, could the Debian mantainers apply a patch to revert that commit?, there is no activity from GNOME developers in the bug report (don't know if they talk about it in mailing lists).
This single click behaviour also happens when selecting a drive on "Other places" of the file dialog. [1] https://bugzilla.gnome.org/show_bug.cgi?id=758065#c19
