tagName is not always in uppercase #6

tagName can be both uppercase and lowercase. An example where it's in lowercase is http://eu.battle.net/en/

document.activeElement.tagName always returns uppercase results, regardless of the input casing. The issue on that page is likely something else.

Developer Tools are telling the different story though: http://puu.sh/qDOqo/fb7ada62f0.png I know it shouldn't be by HTML specification, but anyhow, it's not uppercase.

It's lowercase even in Edge browser :3

You're right! The tagName is lowercase on that website, though I'm not sure why. Here's a reduced test case that doesn't exhibit the issue, yet the battle.net form does have it. I've tried different doctypes, even the whole battle.net page source and it still doesn't exhibit the issue locally, but the live one does. Perhaps there's a script in there that flips Chrome into a quirks mode that I don't know of.

A fix for this issue is coming right up. Thank you for your persistence! :)
