Description hydro-test 2019-07-22 08:47:20 UTC
Writer loads the CPU heavily and the application becomes unresponsive after stretching a table (writing text) inserted into another table in Writer before two pages.

Steps to Reproduce:
1. Create a new document in Writer
2. Insert table (can be in 1 column)
3. Insert one more table into one of the cells of the existing table (it is possible in 1 column)
4. Enter text into the nested table so that it stretches over two pages

Actual Results:
The soffice.bin process starts loading the CPU heavily, and the application becomes non-responsive.

Expected Results:
Not like now.

Reproducible: Always
