3) Select play on the input & output media controls.
4) Select start recording.
5) After three seconds, select pause on both media controls.
6) After six seconds select resume play on both media controls.
7) After three seconds, select stop recording.
8) Select the blob URL

Actual:

I'm sorry, it was brought to my attention this is the intended behaviour. The phone combines the seconds of recorded data into 6 seconds, 3 seconds played, 6 seconds paused, 3 seconds played again.
