Compare results on Windows and Android.

What is the expected behavior?
The expected behavior is what Windows does: the interim result fills up, and after a pause transfers to the final result.

What went wrong?
On Android only, the final result immediately fills up with duplicated text. For example if you say "hello testing", you'll get something like "hellohellohellohello testinghello testinghello testing".

Did this work before? N/A 

Does this work in other browsers? N/A

Chrome version: 57.0.2987.132  Channel: stable
OS Version: 7.0
Flash Version: 

Since it's the same code in both cases, it must be a compatibility problem with Android.
