Right click broken in 45.0
After updating to 45.0 from 44.0, I can no longer right click to set earmarks. Ctrl-click works, but not right click.
Right clicking just does nothing, no popup, or anything.
It seems maybe this is associated with a change from gtk3 to gtk4? I notice the themes/look-and-feel have all changed as well. So I tested that right click does indeed work in the gtk4-demo app, where I can, for example, launch the "Drag-and-drop" app, and right click to add more things to drag around.
