Axes Grid always appears when Ray Tracing is used

Issue where after Axes Grid has been toggled on 1 time, it always appears when Ray Tracing is enabled and can't be hidden or turned off from the Render View.

Steps to Reproduce:

1. Add a Sphere source.
2. In Properties, enable Ray Tracing. Note: that no Axes grid appears here. Toggle Ray tracing back off.
3. In View properties, toggle on the Axes grid, and then toggle it back off.
4. Toggle back on Ray Tracing.

Now we see the grid appears and theres no way to turn it off now as long as Ray Tracing is enabled.
