Accessibility - Zoom - Options have no effect
When using the GNOME magnifier (Zoom) feature the options to control the mouse tracking behaviour have no effect.
Using dconf editor I can see that the value(s) are not being changed. Editing manually works however.
There is no difference regardless of setting "Keep Mouse Pointer Centred", " Mouse cursor pushes" or "Proportional". I've tested this on Ubuntu 18.10, 19.04 and Fedora 29. This is a new bug in GNOME 3.30.
