[144] Button Error based on Layer Visible Status

Link to .capx file (required!):

docs.google.com/file/d/0BzelBqNJ0DazV1NPcWRSYnZFZWs/edit

Steps to reproduce:

1. Attempt to show a layer that is already visible

Observed result:

Error in button_plugin.js

Expected result:

While this is really lame code (in the example) it didn't used to throw an error prior to Beta 144

So I believe it is a bug.

Browsers affected:

Chrome: yes

Operating system & service pack:

Construct 2 version:

144 Beta

Thanks, should be fixed in r144.2.
