Description

After setting up a scripted expression driver, you should not be able to change the 'driven' property using mouse/keyboard input. However, if you type a value in the 'driven' property field, it will override the expression and replace it with that constant value.
I think this must be a bug??

I always thought of this as an oddly designed shortcut to change the driver expression. So I think it might be by design. But I could be wrong.

Wait a minute, you could be right.. Haha!!! yeah, that could be a rather odd design decision but I'd still call it a bug.

It's by design.
