<figure> seems to cause <img> to be resized incorrectly in IE11

Created by: micwic

I just created www.toboggan.me by using Bootstrap4 Alpha5. This site with just on page is public and accessible. I have seen a difference (a bug) in the rendering in IE11.576.14393.0 (W10). I know other IE11 version are also affected. Don't currently know much more. The error is located in a figure tag that allow to render a copyright mention in the first image after the home background image. Just click the chevron down to see the difference.

In IE11 the height is set to the height of the image instead the resized height depending on the row height. MS Edge doesn't have this problem. exportToHTML.zip
