Problem Description:

"Wrap text" should make text in a cell break into multiple lines if text is longer than the cell's width. It displays a text in multiple lines only when the text contains line break (type alt+enter)

Reproducing Steps:

1. in the Spreadsheet, type a text which is longer than a cell's width
2. click the cell and select enable "wrap text"

expected:
text should be displayed in multiple lines in the cell.

Actual:
nothing changed.
