In Outlook emails, textInfos report inconsistent text in some cases

[mltony]

Steps to reproduce:

1. In NVDA Advanced preferences disable UIA for MS Word.
2. Open an Outlook email, see email attached, just remove the .zip characters at the end to open the email. 3.Go to the second paragraph by pressing control+home then downArrow. That's actually an empty paragraph.
3. In NVDA python console:

>>> p=focus.treeInterceptor.makeTextInfo('caret')
>>> p.expand('paragraph')
>>> p.getTextWithFields()
[FieldCommand controlStart with {}, FieldCommand formatChange with {'text-position': <TextPosition.BASELINE: 'baseline'>}, '\n', FieldCommand controlEnd with {}]
>>> p.getTextWithFields()[2]
'\n'
>>> p.text
'\r\x07'

Actual behavior:

p.getTextWithFields()[2] returns a different string from p.text.

Expected behavior:

Text returned by p.text and string elements of p.getTextWithFields() - namely p.getTextWithFields()[2] in this case - should be identical.

@mltony just for completeness, in the email test case attached here unfortunately they use table cels for presentational / design purposes, but these empty cells are not having role="presentation", so NVDA interprets them as empty lines / paragraphs. So maybe there are some specific internals in textInfo on how NVDA threats paragrpahs / characters in table cells which might have to be changed or redesigned.

This issue also affects style navigation in MSWord without UIA - for more info see #16459. I observe exactly the same discrepancy between textInfo.text and textInfo.getTextWithFields(). However the issue with MSWord doesn't reproduce reliably on my computer - whereas the one with Outlook appears to be reliable.
