Initially I added the `suggesting` argument as well, however setting it to false when no candidate panel was required was breaking the code for `needsCandidatePanel()` which would always return false until `inputMethod.activate` would be called again -- the reason for this is that the check for `needsCandidatePanel`  also checks `inputMethod.displaysCandidates()` that returns the `suggesting` argument from `inputMethod`, if it is set to false, only `inputMethod.activate` resets it according to mozSettings.
