Discusion regarding how we make the key-held im module feature work
The discussion seems to be split between kde-gtk-config!9 (closed) and !17 (closed) and other places, so I propose centralizing it here.
I also discovered another wrinkle: when QT_IM_MODULE
is set to anything on Wayland, the virtual keyboard doesn't work. See https://bugs.kde.org/show_bug.cgi?id=411729. And we probably want it to work with virtual keyboards because they're where this feature originated (at least in the mobile world).
