            Bug ID: 205635
           Summary: XMLSerializer doesn't correctly encode entities in
                    <style> element
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: XML
          Assignee: webkit-unassigned at lists.webkit.org

testcase

Please see the testcase, in Safari, it shows:
> <style xmlns="http://www.w3.org/1999/xhtml">/* & */</style>

while in both Firefox and Chrome it shows:
> <style xmlns="http://www.w3.org/1999/xhtml">/* & */</style>

The testcase basically just invokes XMLSerializer's serializeToString to serialize the following element:
> <style>/* & */</style>

and the output from Safari is not a valid XML.
