When we use the lightning:inputRichText component the outputted HTML is generating extra space between lines than what the user sees when editing their text in the component.  This behavior can be demonstrated using the example in Salesforce's own documentation here:

https://developer.salesforce.com/docs/component-library/bundle/lightning:inputRichText/example

Does anyone know how to prevent this behavior?  If not, is this a bug in the comonent?  If so, how are such bugs reported?
