The issue:
An unusual problem occurs when the specified URL is loaded on an iOS7 iPad in landscape mode; a vertical scrollbar appears. There is absolutely no content within the body, and it seems to be adjusting the body/html margin/padding. It should be noted that this test-case is intentionally minimalistic, hence the absence of content and the blank page.
Check out the demo here:

Solutions I've attempted:
I have tried adjusting the viewport settings to:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
as well as
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0">
Additional information:
Unfortunately, I do not have access to an iPad running iOS6 for testing purposes. However, when I tested the demo on an iPad3 running iOS6 using browserstack, no scrollbar was present. Therefore, it seems that this bug is exclusive to iOS7.
Notably, iPhone portrait mode does not exhibit the scrollbar issue, but it does appear in iPhone landscape mode.
