STR: 1. Visit http://www.bloomberg.com/graphics/2015-paul-ford-what-is-code/ 2. Press rightarrow EXPECTED RESULTS: No effect ACTUAL RESULTS: We scroll off to the right (despite the lack of a scrollbar). Chrome & Midori (webkit-based linux browser) give EXPECTED RESULTS. Current firefox release (38) & nightly 41.0a1 (2015-06-28) give ACTUAL RESULTS. This all seems to be due to this HTML: <div id="width-calc"> <div style="width: 100000px; margin-top: 10px;"> ...which is used as part of the "version control" animation in the article. This doesn't trigger a scrollbar because the <body> element has "overflow-x:hidden", but apparently we still make the <body> scrollable via the keyboard Minimal testcase which reproduces this: data:text/html,<body style="overflow-x:hidden"><div style="width: 100000px">Try pressing rightarrow.

Summary: In Bloomberg "What is Code" article, Firefox lets you scroll way off rightwards with rightarrow → In Bloomberg "What is Code" article, Firefox lets you scroll way off rightwards with rightarrow, despite "overflow-x: hidden" on <body> element
Here's a reference case for 'testcase 1' -- tweaked to put the 'overflow-x: hidden' on a <div> instead of on the <body> element. This gives EXPECTED RESULTS. (rightarrow key has no effect)
(Incidentally, if this turns out to be not-a-bug / a tech evang. issue, we can submit a suggested change as a pull request at https://github.com/BloombergMedia/whatiscode/ )
