When I split a cell, and then insert a row anywhere in the table , the new 
inserted row consists of split cell in that particular column.

Steps to replicate the bug:

1)	Create new presentation -->Insert table 5 X 4
2)	Select any cell --> Right click and select cell --> Click Split.
3)	Split cell into 2 and select Direction as ‘Vertical’.
4)	Select any cell in a table and right click, select RowInsert a row(s).

Result: Inserted rows will have that particular column of split cells in the 
inserted rows.

Image is attached.

I feel that this is important to all users since it is very common among 
different kind of users that we split cells and then insert rows.

I also tested this same procedure in Microsoft PowerPoint and didn’t find the 
same result.
