Steps to reproduce:

1. Create a new MS Word document and type the following text:

This is a bold word.

2. Select the word "bold" and press Control+B to mark it bold. NVDA speaks "bold on".
3. Optionally verify by pressing NVDA+F that the word indeed turned bold.
4. Press Home to move the cursor to the very beginning of the document.
5. Press NVDA+space to enter browse mode.
6. Open NVDA Python Console by pressing NVDA+control+z and type:

>>> t = focus.treeInterceptor.makeTextInfo('caret')
>>> t.expand('paragraph')
>>> ff = t.getTextWithFields()
>>> ff[5]
'bold '
>>> ff[4]
FieldCommand formatChange with {'language': 'en_US', 'page-number': '1'}

Actual behavior:

As can be seen in python output, formatChange command immediately preceding the word "bold" doesn't contain any information suggesting that the text is actually bold.

Expected behavior:

TextInfo.getTextWithFields() should return correct formatting information. In particular, ff[4] should contain dict entry 'bold': True, among others.

Name and version of other software in use when reproducing the issue:

MSWord 16.0.17029.20140
This issue reproduces with both UIA enabled and disabled. When UIA disabled indices in ff are going to be different, but the problem is the same: formatChange field immediately preceding the word "bold" doesn't contain 'bold': True entry - as well as all other formatting information seems to be missing.
