What were you trying to do that didn't work?

I noticed that during RHEL-10 installation via RDP, drop down menus open and immediately close after clicking on them. The same problem is possible to reproduce on an installed system - in the preference window of gnome terminal. Both anaconda and gnome terminal are GTK3 applications, AFAIK. I wasn't able to reproduce the problem in the other applications I quickly tried.

See the attached screencast, where on the right side is a desktop running in a VM, on the left side is the same desktop accessed via RDP.

The clients I used to access the RDP sessions were:
freerdp-2.11.2-1.el9
remmina-1.4.33-1.fc40

Please provide the package NVR for which bug is seen:

RHEL-10.0-20240709.23
gnome-remote-desktop-46.2-2.el10
gnome-shell-46.3.1-3.el10
gnome-kiosk-46.0-3.el10
gnome-terminal-3.50.1-6.el10

How reproducible:

Always

Steps to reproduce

1. Run RHEL-10.0-20240709.23 installation in RDP mode (with inst.rdp on the kernel command line)
2. Connect to the installer, try to use drop down menus in the installer - for example on the installation source spoke.

1. Or, on the installed system, enable desktop sharing, connect to the desktop via RDP and use drop down menus on the General tab of the gnome-terminal's preference screen.

Expected results

Drop down menu stays open after clicking on it.

Actual results

Drop down menu closes immediately.
