Description of problem:
Pressing Ctrl+S on a plural translation causes the editor to close then re-open, which causes a lot of movement on screen and could be distracting to translators. 

Version-Release number of selected component (if applicable):
1.6-alpha-1

How reproducible:
Always

Steps to Reproduce:
1.Open the editor for a language with 2 or more plurals
2.Load a document with one or more plurals
3.Focus the editor on a plural
4.Press Ctrl+S
  
Actual results:
Editor closes then re-opens. Height of text flow changes a lot, then returns to previous size.

Expected results:
Height of text flow does not change significantly.

Additional info:
This may also cause problems when the last text flow on a page is a plural, so this case should be checked.
