Hi, 

I saw here https://developer.zendesk.com/api-reference/apps/apps-support-api/modal/ that modals can have a size. The size can be in px, %, or vw/vh.

When I set the modal's size in the code, it does not reflect on the Zendesk webpage.
It always resizes the height.

Is there a ratio that is applied to the modal after the creation?

Also, do the modals have a default size when no value is presented?  

Example:

Thanks!
