Attempt to copy text with Ctrl+Shift+C in Gnome Terminal running under Wayland session of Gnome Shell cause Ctrl+C interrupt for program running under Gnome Terminal

[RussianNeuroMancer]

Hello!

I find that in Gnome Shell 3.29.90 (Wayland session) attempt to copy text with Ctrl+Shift+C in Gnome Terminal cause interrupt (Ctrl+C) for running program. This happen even when I do this inside virt-viewer connection to virtual machine.
Other related hotkeys such as Ctrl+Shift+V, Ctrl+Shift+T also won't work.

A also find that switch keyboard layout with default Alt+Shift cause Opera display it's menu (seems like this is reaction to Alt like it was pressed as separate buttong) which interrupt text typing. Issue is not reproducible if user press Shift first, however many people used to hold Alt first and then press Shift.
