Can't set the mass of collision object

Questions
1

I want to change the mass of collision. I use go.set()

go.set("#collision", "Mass", 5)

And I got this error

'#collision' does not have any property called 'Mass'

But it work when I use go.get()

go.get("collision", "mass") -- 'M' not work. Must be 'm'

go.set("#collision", “mass”, 5) not work too. Why?

Just took a quick look at the source for the collision object component, it appears this is a read-only value. Looks like our newly updated API documentation does not show if properties are read-only or not, we will look into this.

Documentation is updating with this missing information! It should be available in a minute or two.
