Issues resuming timer with pomodoro clock

Tell us what’s happening:
I’m just about finished with the pomodoro clock project, but the free code camp test script is saying that my timer isn’t resuming from the point at which it was paused. However, it seems to me that the pause/play button works fine, so I’m not sure what is causing the issue. Furthermore, when you run the test after you have already played and paused the timer for a little bit, the test says that the timer DOES resume properly, though the test itself is much slower. I’m not sure if there is an issue with my code or with the code camp test or both, so any feedback would be greatly appreciated.

The timer does work, but you need to complete all the user stories, or else it won’t pass all of them.
