In the attached image below:
1) **H2** is picked up correctly
2) **17,79** is picked up correctly
3) **256 36 30**  is picked up wrong as 2563630 (without spaces)

Before this used to work.  Now I am having trouble getting the correct text.  I tried setting the parameters below on getTextContent to true or false, but no luck.

- 	normalizeWhitespace
- 	disableCombineTextItems
- 	includeMarkedContent
