Apparently this issue isn't new with this change, however note that "." (without
a preceding backslash) matches any character not only dots.

Done.

-    if (match && parseFloat(match[1]) >= 14342 &&

It seems parseInt() is more appropriate now. Or simply write |match[1] >= 14342|
and have it automatically converted.

Done.

-        content.classList.contains("edge"))
+    var match = window.navigator.userAgent.match(/Edge\/\d+\.(\d+)/);
+    if (match && match[1] >= 14342 && content.classList.contains("edge"))
       content.classList.add("edge-supported");
   }
 
   init();
 })();
