webbrowsertools.com detects actual useragent with aggressive iframe UA check #173

Reported warning: UA string detected by [normal] navigator.userAgent is different from UA string detected by [aggressive] iframe navigator.userAgent

Turns out that the user agent reported in javascript is for a split moment unchanged when loading an iframe, allowing sites such as creepjs or webbrowsertools to get your original user agent provided it is retrieved fast enough.
