Framework: Custom elements attached method not working when it is placed inside layout slot

[ricbermo]

I'm submitting a bug report

• Library Version:
  I'm not sure about it but on my package.json I found 1.0.0-rc.1.0.0
• Operating System:
  OSX 10.11.6
• Node Version:
  6.2.2
• NPM Version:
  3.9.5
• Aurelia-CLI
  0.17.0
• Browser:
  Chrome 52.0 | Firefox 48.0 | Not tested in others
• Language:
  ES2015

Current behavior:
When placing a custom element inside one of a layout slots the attached method is never called, but is I place the same element outside the layout the method does get called. I must add that the element is created and is functional but that callback, than in this specific case I am needing, is not called.
I created this gist to show the issue. Notice I used the custom element twice. One inside the layout and the other outside it.

I found this issue while playing a little with Aurelia.
This is the repository link: https://github.com/ricbermo/super-gym-client-aurelia
Feel free to fork it and use it for debugging or w/e.

Expected/desired behavior:
I expect the attached callback get called when a custom element is used/placed inside a layout.

@jdanyow would you mind looking at this and the linked issue above? @ricbermo contacted me from reddit about this issue.

@charlespockert We've had a couple of people report this issue. Since you did the original work to enable the layouts, would you be willing to look into this bug and attempt to fix it?

What is the status regarding this issue? Is there any progress so it'll be possible to use layouts in future versions of Aurelia?

It should be fixed. This was s dupe issue and didn't get closed when the original issue was resolved.
