Moving this to the aptdaemon package, as update-manager is using the gtk3 widgets from that package. The problem here is that the downloads progress treeview uses the native gtk treeviews tooltip_column mechanism, which creates standard gtk tooltips from the given column (in this case the URI of the download), but has the word_wrap attribute set to True without an easy way to change it. The only option seems to use custom widgets (a Gtk Label with wordwrap set to false) in the tooltips displayed by the treeview.
