[BUG] Bounds Control gets active when object manipulator is disabled

[Maesla]

Describe the bug

Bounds control gets active in the state "Focus" if the bounds control is visible and object manipulator gets disabled

To reproduce

Steps to reproduce the behavior:

Bounds Control Bug.zip

1. See the attachment "Bounds Control Bug.zip". Unzip it and add it to the project
2. Open the scene "Bounds Test.Unity"
3. Click "Play"
4. See how the cube gets selected, and, while is selected, the manipulator gets disabled.
5. See how the cube keeps the "Focus" state of the bounds control
6. Stop the execution. Go to the GameObject "Debug" and click "Hot fix" in the Bounds Test. Play again
7. See how now the behavior is correct

Expected behavior

The bounds control disappears when the object manipulator is disabled

bool handlesActive = boundsControl != null && boundsControl.HandlesActive;

HandlesActive returns true when object manpulator is disabled. Because HandlesActive is true, targetActiveFocus is 1, so the focus state stays

Why does HandlesActive become true when the object is disabled? I am not sure but this is the callstack. OnHostDeselected inverts the value of HandlesActive , and, because it was false, now it is true

As a workarround, you can do boundsControl.HandlesActive = false; after objectManipulator.enabled = false;
