Textbox always on top of Layout

Link to .capx file (required!):

dropbox.com/s/y33trfjfidy9elg/textBox.capx

Steps to reproduce:

1. Define a Textbox at first layer

2. Cover the Textbox with an other Object on a "higher" layer

3. Set the layer on top visible

Observed result:

The Textbox is always on top of the layout. I can't display information to the user on an other layer until destroying the Textbox.

The .capx is only a small demo of the problem because I can't post the whole source code, but the problem is still the same.

Expected result:

I thought that the Sprite in Layer 1 will cover the Textbox on Layer 0 so that I can show information to the user after click at the Button and then go back to the original mask.

Closing as won't fix. It's not possible to resolve this, because form controls actually float above the canvas where sprites are rendered.
