SQL Editor Tabulator ignored line

Just installed the version 13.1.1.5 and found new behavior in sql editor window. When copied a statement that includes lines with a tabulator in the last line, line will be ignored, more worse statement will be executed with wrong, e.g. no result !!

SELECT *
FROM Table A, Table B
WHERE A.id=B.id
and A.id=1

Result 1 line, ok

SELECT *
FROM Table A, Table B
WHERE  A.id=B.id
<TAB> and A.id=1 

Result no rows, wrong !!

Interesting:

SELECT *
FROM Table A, Table B
WHERE
< TAB > id=1
and A.id=B.id

Result 1 line, ok

Something in option settings ? A bad behavior, because you can't see the
