If the translation of the last message on any give page is long (more than ~5 lines), the whole workspace will constantly jump up and down a bit (as in, the scroll bar is juming up and down) with every typed letter. The longer the message, the worse it gets.
In older Zanata versions it was entirely impossible to display those last lines of a long, last message. Now it is possible, but the view sort of quivers before your eyes, making it hard to focus.

Reproducible: Always

Steps to Reproduce:
1. Open workspace for any document
2. Open very last message on any given page
3. Enter a translation that is longer than ~5 lines.
Actual Results:  
Workspace should give a steady view

Expected Results:  
Workspace quivers when scroll bar jumps up and down in order to keep up with the longer message
