Description:
Text with internal line breaks may overflow from fixed-size cells

Steps to Reproduce:
1. Open new Calc.
2. Insert 3 lines text in Cell [A3].
  (ex.)
aaa
bbb
ccc

3. With the default setting, the cell will automatically expand vertically to fit all text inside the cell.
4. Manually shrink to the original line height.

Actual Results:
5.  In the standard setting, it overflows from the cell and appears on top.

Expected Results:
5.  The cell does not overflow, only the last row "ccc" is displayed.


Reproducible: Always


User Profile Reset: No

Additional Info:

In the merged cell, it also overflows horizontally. The overflow mark is displayed at that time.

The sample file contains two: "Manually reduced cell height" and "Merged Cells".
