Question: why these commands opens in a new Split but Split closed after finished the process?

Linux Mint 21.2 MATE
Tlix 1.9.4
Kernel: 5.15.0-88-generic
Shell: bash 5.1.16
WM: Metacity (Marco)
Theme: Adwaita-dark [GTK2/3]
CPU i7-4790
GPU AMD ATI Radeon R9 290/390

Bash:

:~$ tilix -a session-add-right -x "lsof -V" :~$ tilix -a session-add-right -x "neofetch"`

I enter one of this Bash above, the Split opens, then the Process is working until it finished, then the Split closes.
No warnings or error.

Isn't that the desired behavior? I always thought that's just what -x did?

if i use
tilix -a session-add-right "whoami" -x
an empty split opens and stay open, i try it with an without "-x"
i think its broken now...no error or issue messages
