Integration button elements do not work.

Bug description

There is a difference in loader styles between the edit and published views for button components. This is causing most users to experience "panic clicking" resulting a 500 back from GitBook if the button is clicked twice in a row. There may be two issues here. Firstly, the button component does not render a loader and lock out the button from being clicked twice. The second, a server side issue with CloudFlare causing a 500 to result when two requests a simultaneously being processed.
