Steps to regenerate
When I have the Enable Table Cell Merge set to true, I open the application and I insert a table and the cell selection works fine; however, when I click new document and create a new document and insert a table again the selection does not work.
If I close the application and reopen it, the table cell selection will work for the first time, but it does not anymore after a new document is created or a file is opened.
Basically, I am not able to select any cell after the a new document is created or a new file is opened. It happens every single time.
