Clean ist worse

I have the following code in my fluid-Template

    <script>
        var ivmmontlystatisticsInitTableDatas = ivmmontlystatisticsInitTableDatas || {};
        ivmmontlystatisticsInitTableDatas.dataSet = JSON.parse({jsonTableDataString->f:format.raw()});
...

If i try to commit, the cleanup removes the colon ; and the f:. I store in git.

    <script>
        var ivmmontlystatisticsInitTableDatas = ivmmontlystatisticsInitTableDatas || {};
        ivmmontlystatisticsInitTableDatas.dataSet = JSON.parse({jsonTableDataString->format.raw()})
...
