This adds a reference to the Gtk3 source created by GLib.idle_add so it can be checked to see if it was destroyed later to avoid removing an invalid source id and causing warning messages to be displayed.
Seems reasonble to me @fariza any comment?
👍 I see no problem with this. Thanks for the fix

I'm using matplotlib in a GTK3 application (backend is set to GTK3Cairo) and when my application exits I consistently get the following warning:
Looking into the issue it looks like the idle_event is removed and thus when
GLib.source_removeis called, the event id no longer exists. It would be great if a check could take place before the event source is removed to determine if it is still valid.This PR adds a reference to the Gtk3 source created by GLib.idle_add so it can be checked to see if it was destroyed later to avoid removing an invalid source id and causing the aforementioned warning messages to be displayed.
