BUG: Panels "visible" attribute doesn't prevent panel rendering

Version:

v0.17.3

Are you able to reproduce the bug from the demo?

• Yes
• No

What is the expected behavior?

editor.Panels.addPanel({id: 'test', visible: false}) renders panel despite of visible attribute set to false. It perfectly works after editor has been rendered, so panel.set('visibility', !panel.get('visibility') toggles visibility correctly.

Workaround 1 to set gjs-hidden class with visible: false together didn't work too. This way visibility would be checked later and gjs-hidden class would be removed. At least is this the behavior I see.

There was same issue already: #1602.

Workaround 2 to call toggleVisibility function just after panel has been created didn't work too. I think it's because render() function in the PanelView overrides classes. Even to set class manually like it's done in the toggleVisible function didn't work.

What is the current behavior?

Visible attribute is set correctly to false in the panel when I get it using editor.Panels.getPanel('test') but panel itself is still visible until panel.set('visible', false) call after editor has been rendered.

Are you able to attach screenshots, screencasts or a live demo?
