Description of problem:
TM pane is extended when a translation memory contains a long string which cannot be wrapped.
It makes extremely difficult to read the information.
You need to scroll to the right to be able to read one line, and when you need to see the next line, the beginning of the next line is invisible and have to scroll back.

Version-Release number of selected component (if applicable): 3.3.2


How reproducible: always


Steps to Reproduce:
1. Find a long string that is not broken with spaces
2. Check TM pane


Actual results:
It stretches beyond the width of the window


Expected results:
It should be wrapped so that you don't need to scroll side to side.
