Details:

Running Octave 5.1, started via Flatpak, on a remote host over SSH does not
work properly. Pressing Ctrl-C results in a weird behaviour, partially
disconnecting the terminal from the Octave instance.

Note: The OS is Ubuntu 18.04.

The terminal output below intends to demonstrate this.
To reproduce, it's a matter of:
- Connect to remote host via SSH
- Start Octave using Flatpak
- Press Ctrl-C

Pressing Ctrl-C seem to partially disconnect the terminal from the Octave
instance, although the latter seem to still be running.
The regular Bash prompt is seen, but also (sometimes) an Octave prompt.
The Octave process also still seems to be running until I kill it.

I'm so used to pressing Ctrl-C in Octave (to abort a command line) that this
problem makes Octave/Flatpak unusable for me over SSH.


local-host$ # First connect to a remote host, with X11 forwarding
local-host$ ssh remote-host


$ # On remote host, start Octave
$ flatpak run org.octave.Octave
GNU Octave, version 5.1.0
