Every iframe seen on the page has it's own kept
alive connection to the server and updates the
CSS inside itself to blink the background.
This visualization indicates the active connection.
Only 6 out of the 9 displayed iframes however
should start blinking, as the miniscule connection
limit keeps their requests in a pending state.
