The current behavior

Inconsistent number of new lines in between paragraphs in $getRoot().getTextContent() output.

The expected behavior

Consistent number of new lines in between paragraphs in $getRoot().getTextContent() output.

Impact of fix

I am using $getRoot().getTextContent() to get text diff between initial and final state. The inconsistencies report fake addition/removals of new lines.
