How to reset the size of the WWTJupyterWidget?

[hickst]

The attached screenshot shows the issue: I want to change the size of the WWTJupyterWidget. I try to reset the 'layout' property and, while the widget does change size (the white part not covered by black content), the content does not fill the widget. I've tried various Layout options but none seem to have any effect. Is it possible to resize the WWTJupyterWidget?

Is there a PyWWT Slack channel (or something similar) I could have asked this question on instead of filing an issue?
