This seems to be the behavior currently in Anki:

https://github.com/dae/anki/blob/master/anki/collection.py#L523
  fields['FrontSide'] = stripSounds(d['q'])

Since this is a function in libanki, I would rather avoid diverging from it.
@hssm what do you think?

Also, what's the behavior on Anki on the desktop?
