Functional notes:
The Gif in the center channel should run 6 times, and then pause itself with the Gif
button on top of it.

Clicking the button will run the Gif again for 6 times.

Clicking or tapping the Gif anywhere would first play it, if its not already playing.
And if is playing, then a modal will open up with the Gif playing indefinitely.

I would also like to work on this issue, if it's still up for grabs!

I've assigned this to @Prescise as he commented first, but let me know if you want me to change the assignee at any point.

It's okay. If it opens up again, I'd like to contribute :)
