Due to the extra delays added by setting up the closed captions, it happens more
often that the writing.js code will attempt to initialize popcorn on the video
element before the video element actually exists on the page.

(This was always a problem, it's just worse now)

Add a synchronization point which will delay the popcorn initialization until the
video element is ready.

This can create weird conflicts when using other libraries

UI Changes Update

The reason there was so much space between `Join Audio` and `Status` was that `Join Video` was in between. Join Video was removed
to fix this positioning.

Leave Audio and Join Video icons are being hidden, which still holds the space for that component in the DOM, but does not show
it.
`Join Audio` should not be commented out because the icon is displayed at certain times.
`Join Video` can be commented out for now for UI purposes and put back when it's implemented.
