The draft conflict dialog is blinking when opened (appears and disappears a couple of times). Closing it does not close it fully - the background stays grayed out.

Steps to reproduce:
1. Login as admin
2. Go to Content -> Content structure
3. Start creating a new Article - fill the required fields
4. Select "Media" in the relation field
5. Publish
Note: the notification that the Content has been published is displayed twice
6. Start editing the Content Item again
7. Exit the editing view by clicking the Back button
8. Click "Edit"

Expected:
Draft conflict dialog is displayed without any issues

Actual:
Drfat Conflict dialog opens several times?
