Steps to reproduce the problem:
1. search for "opressed deutsch". Note: only this typo seems to produce this error.
2. Hit Enter
3. Look at the translation box.

What is the expected behavior?
Normal translation.

What went wrong?
The "german box" included "~~POS=HEADCOMP". 

Does it occur on multiple sites: N/A

Is it a problem with a plugin? N/A 

Did this work before? N/A 

Does this work in other browsers? No Firefox 48.0.2 & Firefox 49.0.1

Chrome version: 53.0.2785.116  Channel: n/a
OS Version: 10.0
Flash Version: Shockwave Flash 23.0 r0

I tried this with other words/typos, it seems to be a problem with this (and only this) word. adding another word puts the translation after the ~~POS=HEADCOMP. Example:

oppressed peopl ->
drückten~~POS=HEADCOMP peopl
