Library component sidebar preview messes up aspect ratio of images

[bradenmacdonald]

When an image is included in a Text component with an explicit width and height, like TinyMCE does by default:

<img src="http://studio.local.openedx.io:8001/library_assets/component_versions/f12c83a3-2aab-4599-a145-eab778cc62a4/static/XBlock%20Distribution.png" alt="Example" width="1294" height="837" />

Then when it appears in the preview, it will have the specified height but the wrong width, resulting in a distorted aspect ratio:

I failed to reproduce this using the Text component.

@kdmccormick @rpenido I figured out how this happens and updated the description.

I reported the original bug and can confirm it is now fixed on the sandbox.
