Steps to Reproduce
0) Use IE11
1) Add a web content display to a page and use the plus button to create basic web content
2) Add two paragraphs of text. Add an image.
3) Align the image left try to use the cross hairs to move the image
4) Drop the image
5) If it didn't reproduce the first time, continue moving the image back and forth until it reproduces.
Expected Result: Image does not leave the content section.
Actual Result: Image sometimes does not drop where intended, and instead is placed outside of the content section and gets stuck (usually next to the Title section).

I believe adding the text and image when reproducing is relevant. I cannot reproduce with a WC that's already created with the text and image.
