Title:
xterm resize is wonky

Bug description:
[ Impact ]
When I try to resize an xterm window the same way,
this happens instead: as the mouse is moved, the upper-right corner
does move, but it doesn't track with the mouse pointer like it should.
Meanwhile, the lower-left corner also moves (it should have remained anchored
in its original x-y position on the screen).
[ Test case ]
- Start Xterm
- Resize the window from its top/left corner
- It should resize normally, and not act as shown in
https://gitlab.gnome.org/GNOME/mutter/uploads/3c19763b7748ce76b0ba2958cde7636b/Screencast_from_02-04-19_14_03_24.webm
[ Regression potential ]
Windows resizing might not work correctly

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04 LTS
Release: 20.04
Codename: focal
% wmctrl -m
Name: GNOME Shell
Class: N/A
PID: N/A
Window manager's "showing the desktop" mode: OFF
Terms:
window has four sides: top, bottom, left, and right
when referring to corners, "upper" means "top", and "lower" means "bottom",
so the four corners are upper-right, lower-right, lower-left, and upper-left.
wonky: works wrong, as detailed below ("cases that work wrong...")
Description:
I can resize a gnome-terminal window, everything works fine.
(Grab it, using the mouse, by the upper-right corner (click-and-hold);
the size changes as the mouse is moved, because the position
of the upper-right corner follows the mouse. (Only the upper-right corner
moves.))
But when I try to resize an xterm window the same way,
this happens instead: as the mouse is moved, the upper-right corner
does move, but it doesn't track with the mouse pointer like it should.
Meanwhile, the lower-left corner also moves (it should have remained anchored
in its original x-y position on the screen).
Cases that work correctly:
If the xterm window is grabbed by the lower-right corner and resized, this
case works properly.
If the xterm window is grabbed by the bottom edge and resized, this case
works properly.
If the xterm window is grabbed by the right edge and resized, this case works
properly.
Cases that work wrong ("wonky"):
If the xterm window is grabbed by the left edge and resized, then the
opposite (i.e. right) edge (incorrectly) migrates.
If the xterm window is grabbed by the top edge and resized, then the opposite
(i.e. bottom) edge (incorrectly) migrates.
If the xterm window is grabbed by the upper-right corner and resized, then
the window (incorrectly) migrates.
If the xterm window is grabbed by the lower-left corner and resized, then the
window (incorrectly) migrates.
If the xterm window is grabbed by the upper-left corner and resized, then the
window (incorrectly) migrates.
