Description:
In Writer, after applying format to text inside a table, if I click on the 'Rows Below' button to add a new row wherever in the table, the text of the whole table reverts to the default Liberation Serif 12pt format.

Steps to Reproduce:
1. Open Writer.
2. Insert table.
3. Write anything on the table.
4. Change format (font, size, bold, italic, color) of the text inside the table.
5. Insert row below (using the button on the toolbar, or in the context menu)

Actual Results:  
The text reverts to the default format (font: Liberation Serif, size: 12, color: black, font-style: normal).

Expected Results:
Add a new row below, while keeping the previous text formatting.


Reproducible: Always
