NVDA leaves a table when browsing blank cells in MS Word with UIA enabled

[brunoprietog]

With UIA enabled for Microsoft Word, when you navigate a table that contains empty cells, NVDA leaves the table as it passes through that cell, using the Alt+CTRL+Arrow navigation commands. If you navigate only with arrows, for example, with a right arrow to move to that empty cell, it does not report the cell/column/row change.

Steps to reproduce:

With UIA enabled, insert a table in Microsoft Word and try to navigate it with the table navigation commands, or just the arrows. NVDA does not identify the cells.
If you type things into any of the cells and leave other cells empty, you will be able to move correctly through the cells that have text, but you will not be able to move through the blank cells, NVDA leaves the table or does not announce the cell change.

Actual behavior:

NVDA does not identify the blank cells, leaves the table or does not announce the cell change.

Expected behavior:

NVDA announces the cells correctly.
