Terminal Title Disappears in Gnome Terminal Fedora (Bug)

I’m using manjaro gnome. I disabled auto generation of terminal title when idle by commenting out ZSH_THEME_TERM_TAB_TITLE_IDLE= & ZSH_THEME_TERM_TITLE_IDLE= in manjaro-zsh-config .
During the execution period of a command, i.e. ‘pacman -Syyu’ the terminal title shows the running cmd & after completion the terminal title is just ‘Terminal’ . But in ‘Gnome terminal Fedora’ after the execution period of a cmd the terminal title disappears( just blank space ), not showing ‘Terminal’ again like the stock gnome terminal did. I think this is a bug in Gnome Terminal Fedora.
