demo of the bug in action

Description of problem:
I default to opening a gnome terminal window at 80x24.  But when I maximize a terminal (sometimes by accident when double- instead of single-clicking on the top bar of the terminal window), restoring the window back to its original dimensions loses a row and column.  This only started happening when I upgraded to Fedora 30 (it did not happen on F29).

Version-Release number of selected component (if applicable):
gnome-terminal-3.32.2-2.fc30.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Open a terminal window, and observe its dimensions (I did this by clicking the mouse on the bottom right corner, but not dragging)
2. Maximize the window by double-clicking the top bar
3. Restore the window by double-clicking the top bar
4. Check the size again

Actual results:
Each cycle reduces the size of the window

Expected results:
The restored size should match the original size
