I didn't really want to move the cursor in front of the HUD, but we face
a bit of an impossible scenario otherwise (it should definitely be in
front of the break overlay for visibility).
So I'll deal with it for now.
In testing I can't find a reason for this to exist. Blaming back shows
that it existed before we had `AllowTrackControl` and was likely being
used as a stop-gap measure to achieve the same thing. It's existed since
over 6 years ago.
Let's give removing it a try to fix some usability concerns?
