Qt Keyboard Shortcut: Fullscreen incorrectly mapped in GNOME

A keyboard shortcut within Qt applications running under the GNOME desktop environment is incorrectly registered or handled. The shortcut is expected to be F11 is instead requiring Ctrl+F11 to activate the associated action. I don't know where the Ctrl+F11 comes from, I tried to find a source but all gnome help refers to fullscreen as F11 such as:

https://help.gnome.org/users/gnome-terminal/stable/app-fullscreen.html.en#:~:text=Press%20the%20menu%20button%20in,Full%20Screen%2C%20or%20press%20F11%20.
