Observation on Ubuntu 18.04 :
- All work good on Xorg session
- Problem only affect Wayland session
- Classic windows with traditional decoration (chromium, pidgin, inkscape, ...) accept middle-click action
- GTK3 apps with Headerbar decoration who use CSD (Client Side Decoration) ignores middle-click
- Don't know why, but Evolution 3.28.1-2 ignores middle-click too (but have traditional decoration !)

Freedesktop talk about that since December 2016 : https://lists.freedesktop.org/archives/wayland-devel/2016-December/thread.html#32028
