Can't move (or see) the mouse cursor during desktop zoom

Bug description:
[ Impact ]
The "Desktop Zoom" accessibility feature loses track of the mouse
cursor when using the following settings:
- Magnifier position:
- Screen part: full screen
- Magnifier cursor pushes contents around
- 'caret-tracking' and 'focus-tracking' set to 'none'
When that happens, the cursor is not visible and the zoomed view does
not move with the mouse.
[ Test Plan ]
1. Configure the zoom feature with:
$ gsettings set org.gnome.desktop.a11y.magnifier mouse-tracking push
$ gsettings set org.gnome.desktop.a11y.magnifier caret-tracking none
$ gsettings set org.gnome.desktop.a11y.magnifier focus-tracking none
2. Log out and log back in
3. Open a Terminal window (having an active caret is required to trigger the
bug).
4. Enable the desktop zoom effect with Super+Alt+8
5. Move the mouse cursor from one edge of the desktop to the other
6. Verify that the cursor is still visible and that the zoomed view moves
when the cursor is moved to the edges.
To reset the zoom feature configurations to the default you may run:
$ gsettings reset org.gnome.desktop.a11y.magnifier mouse-tracking
$ gsettings reset org.gnome.desktop.a11y.magnifier caret-tracking
$ gsettings reset org.gnome.desktop.a11y.magnifier focus-tracking
[ Regression Test Plan ]
1. Reset the desktop zoom configuration to the default, as above
2. Enable the desktop zoom effect with Super+Alt+8
3. Verify that the zoomed view moves together with the cursor
[ Where problems could occur ]
The patch only affects the zoom effect and will not have side-effects
on other uses of the desktop. When using the zoom effect problems may
manifest with incorrectly tracking the mouse position.
