BUG: (0.16.41) Components have lost their styles

Version: 0.16.41

Are you able to reproduce the bug from the demo?

[X] Yes [ ] No

What is the expected behavior?

1. Copy selected parent component (container) to the clipboard.
2. Paste selected parent component (container) from the clipboard (into the same page or an other page).
3. All components keep ID styles and inline styles.

What is the current behavior?

1. Copy selected parent component (container) to the clipboard.
2. Paste selected parent component (container) from the clipboard (into the same page or an other page).
3. Components have lost their ID styles, but not their inline styles.

Components don't have a regenerated style ID, but the same previous ID with a "-2" appended.

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

[X] Yes (attach) [ ] No

From the jsfiddle above, follow the next steps :

1. Select one component.
2. Copy this component with Ctrl/Cmd + C.
3. Paste the copied component with Ctrl/Cmd + V.
4. All defined style have lost, inline style have preserved.
