I'm not really sure whether this is supported or not. If not please do not close yet we should document and ass to release notes first.

Perhaps related are Fedora bug 1512564 and bug 1479682 ?

One note here, remote-viewer/virt-viewer/gnome-boxes can run natively as wayland clients on Fedora, and this issue with keyboard events only happen when they are explicitly run with GDK_BACKEND=x11.
On RHEL7, they always get run through Xwayland, not as native wayland clients?
