IllegalStateException on node save to HTML

I have a paragraph Node. When I try to save this Node to HTML using the toString(SaveFormat.HTML) method, I get the following error:

java.lang.IllegalStateException
	at com.aspose.words.zzZSV.endElement(Unknown Source)
	at com.aspose.words.zzZU8.endParagraph(Unknown Source)
	at com.aspose.words.zzZWU.zzD(Unknown Source)

	at com.aspose.words.Node.toString(Unknown Source)
	...

Using deepClone seems to work around the issue i.e. this works just fine:

p.deepClone(true).toString(SaveFormat.HTML)

Using Aspose.Words for Java 18.8.
