Steps to reproduce:
1. Start portal and login.
2. Add calendar portlet to home page, add event.
3. Press the image button, try to insert a image to the content of calendar event. (user can upload any image using DM).
The image can be displayed in content part.
Nothing shows up.
1. Found this during testing 7.2 FP9(build4) FixPack bundle. Can not verify on 7.2 FP9(build3) since it is blocked by
LPS-122634 on build 3.
2. I have not tested it on latest 7.2.x and master since it too slow to download the bundle.
