containerProps is missing in 4.0.0-beta.2

[retromack]

In version 4.0.0-beta.2 the containerProps prop appears to be missing or no longer supported. This prop was previously used to pass HTML attributes (e.g., style, className, id) directly to the chart container

.

Hi, thanks for reporting this. We will look into adding this back before the full release.
