Internet Explorer 11 (IE11) returns null for deviceFound if manufacturer codes are in the user agent

[argentini]

User agents in IE 11 like the one below work fine:
"Mozilla/5.0 (Windows NT 6.1; Trident/7.0; rv:11.0) like Gecko"

Ones that include manufacturer codes (like MALC below) cause evidence.deviceFound to return null.
"Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; MALC; rv:11.0) like Gecko"

The manufacturer codes at the URL below may need to be accounted for when IE11 is processed. Adding null checks and assuming desktop may be a decent workaround, but it's not accurate or a long-term solution. Thoughts?
