bug(compatibility): gemini-scrollbar + AddToAny

(Also, I notice AddToAny author)

1. Summary

I can't use gemini-scrollbar + AddToAny default style. I have a critical bug: full web page not displayed correctly in most browsers.

I have expected behavior, if I use:

native browser scrollbar instead of gemini-scrollbar;
a2a_floating_style, not a2a_default_style.

2. MCVE

    return

window.onload = internals.initialize
window.onorientationchange = internals.handleOrientationChange
