Yet it doesn't spoof the other `navigator.*` properties amiright? Over 90% of the size of this extension is a stripped down version of the Browscap User-Agent capability database that we use to infer the required extra information based on the given User-Agent-String. Not trying to convince you or anything, but I thought an explanation of why this is happening may be in order. :-)

I'm not sure what you are complaining about, but the above is a “Windows 7 64-bit running Internet Explorer 11 32-bit” user-agent. I see nothing unexpected with this result.
