In tablet mode, step "Who are you" OSK hides when the password field is focused

[Jean-Baptiste Lallement]

Test Case:
1. On a 2 in 1 in tablet mode, launch the installer and proceed to the user setup step (Who are you)
2. With the OSK, enter the username, login, hostname and password then proceed zith the rest of the installation

Actual result
The OSK hides when the password field has the focus and the user cannot enter a password.

It might be a gnome-shell/OSK issue, sound similar to some of the issues Andrea was looking at where ... Andy, could you have a look once you are done with helping Marco with the boot issues?

[Andrea Azzarone (azzar1)]

That's a known regression from commit https://gitlab.gnome.org/GNOME/gnome-shell/commit/fc5ab4470445992b1ad4338290deb24e6b1c5ce2

My suggestion is to revert the commit even if upstream disagrees. Their argument is that there are performances issue with the old behaviour (in a nutshell AtspiEventListener spams the dbus channel quite a lot), my argument is that osk is completly broken under xorg.

Maybe merge with bug 1760399?

Would be nice to fix but it was decided to not be important enough at the moment to rls target, tagging -notfixing
