[Typo3] Text tools fix?! (web>func, Text tools)

[T.Joga]

Hello!
Is there "searchLevels" fix for Text tools?
I have already made this fix:
http://typo3.org/documentation/document-library/cc_textfunc/Known_problems-6f3691a150/

Problem is that Text tools allows only one level changes because Search 
  Levels selector doesnt work.

There is around line 148 this:
$this->mkSelect('SET[tx_cctextfunc_modfunc1_searchLevels]',$LANG->getLL('enterSearchLevels'),$this->pObj->MOD_SETTINGS['tx_cctextfunc_modfunc1_searchLevels']). 


I tried this:
$this->mkSelect('SET[tx_cctextfunc_modfunc1_searchLevels]',20).

...no cake.


My Typo3 version is 3.8.
