Impossible to do XMLQUERY for Oracle databases

I've been trying out DataGrip as a replacement for TOAD but have hit a rather large snag with the string wrapping in the code editor.

-- What I want
SELECT 
 XMLQUERY('
copy $temp := $data/*
modify (
 replace value of node $temp/FOO with $foo 
)
return $temp
 ' 
 PASSING 
 XMLELEMENT("ROOT",
 XMLELEMENT("FOO", 10)
 ) AS "data",
 12 AS "foo"
 RETURNING CONTENT
 )
FROM dual

-- What I get
SELECT
  XMLQUERY('' ||
    'copy $temp := $data/*' ||
    'modify (' ||
      'replace value of node $temp/FOO with $foo ' ||
    ')' ||
    'return $temp'
    PASSING
      XMLELEMENT("ROOT",
        XMLELEMENT("FOO", 10)
      ) AS "data",
      12 AS "foo"
    RETURNING CONTENT
  )
FROM dual

The second errors because the XQuery is missing whitespace. Is there any way to disable this behavior?
