Video component does not add Source property information to project

[rodenp]

I cannot seem to get the Video component to work in designer. I used the following as an example -> https://storybook.grommet.io/?path=/story/video--simple I copied the following from the 'source' tag into the Source property of designer. src="http://techslides.com/demos/sample-videos/small.mp4" type="video/mp4" The video component partially displays, but does not play and NaN:NaN displayed in the control.

When i inspected the generated React code there was no 'source' tag anywhere to be seen. Adding the 'source' tag to the generated React code resolved the issue.
