"Touching mouse pointer" always returns false when the sprite is hidden

[thisandagain]

Expected Behavior

In Scratch 2.0 it returns true if it's over the sprite, even if the sprite is hidden.

To test, add and run these blocks:

Then hide the sprite, mouseover it, and show it again. It should have moved.

I was able to track this back to the pick method in the renderer. Essentially the pick method is ignoring the drawable when it is hidden. This behavior often makes sense, but not in this case.
