I don't think any program can "address" this long-standing issue, as
long as said program uses GTK+, which dies whenever a display connection
closes underneath its nose.

Some time ago, I worked on a port of feature/pgtk to GTK+ 4, which
exhibited the same problem.  I'm not quite confident that situation will
change any time soon.
