13545	Error is thrown when creating one embed content on another.	Jakub Ś		"1. Use these three plugins embed,embedsemantic,autoembed.
2. Empty the editor.
3. Please (**Ctrl+V**) this link into editor: https://twitter.com/reinmarpl/status/573118615274315776 (the non-semantic Media Embed is created )
4. Select created widget by clicking on it
5. Open Semantic Media Embed Dialog, paste the link and click OK.
**Expected Result:** Non-semantic Media Embed should be changed to  Semantic one.

**Actual result:** JS error is thrown.

Since it works when doing this with dialogs I'm guessing that autoembed plugin doesn't report widget/content to some list.
