iOS iPhone webapp: Replace Checkered/Transparent Background on Rotate

[iTim314]

When rotating my webapp (fullscreen mobile Safari), a checkered ("transparent") background appears where the content is/has shifted on rotate.

Is there anyway to make this background completely black? I've tried:

html, body { background-color: #000000; }

Doesn't work. See screenshot if you're unsure as to what I'm talking about...

I just tried rotating Safari and noticed the same thing. That seems to be a Safari issue, which means it is out of your hands.
