After toggling fullscreen the window restores to a window that fills the screen instead of the original size

Description

Expected Behavior: When pressing F11 in xfce4-terminal, it should toggle between fullscreen and the original size of the window

Observed Behavior: Pressing F11 enables fullscreen and pressing it again briefly flashes the window at the correct size then the window (with window borders enabled) fills the screen minus the xfce panel.

Always the first 3 toggles work properly but then once it's un-fullscreened incorrectly once it never works properly again until I completely restart the xfce4-terminal process.

The same bug happens when using the regular window titlebar maximize/unmaximize buttons.

I've confirmed this behavior on versions 0.8.6 - 0.8.7.4.
It doesn't happen on versions 0.6.3
It doesn't happen when using xfwm4
I'm using Openbox 3.6.1 as my window manager
All my testing was using Xubuntu 18.04.1
No other windows or terminal emulators that I've tested (sakura, xterm, xfce4-notes, xfce4-settings-manager) exhibit this bug

My workaround is to use v0.6.3 for now.

Version: 0.8.7.4
