gnome-terminal does not fill screen when window snapping on Wayland in Ubuntu 17.10

[Nicholas Stommel]

When using a Wayland gnome-session or Wayland ubuntu-session in Ubuntu 17.10, gnome-terminal (v3.24.2 is the version in the 17.10 repositories) does not fill the screen at all when snapping the window to the right or left side. There are large gaps on the right and bottom edges of the terminal window in Wayland. On the same computer, with the same version of gnome-terminal in an Xorg gnome-session or Xorg ubuntu-session, the window fills screen space entirely and there is no problem. I am not using display scaling or hidpi features at all, my display resolution is set at default 1080p. This needs to be fixed or I'm ditching gnome-terminal.

Expected behavior: gnome-terminal window should fill right/left of screen when snapped to corner in a Wayland session
What happened instead: gnome-terminal window does not fill screen space when snapped to right or left edge of desktop on Wayland session, there are large gaps below and to the right of the snapped window on either side.

Ubuntu has just released libgtk-3-0 3.22.25 as an update to Artful, which I believe should fix this bug.
