regSaveParamJson: using regular expression in queryString property

hi,

i have web script in javaScript which having complecated Json responses to correlate

does loadrunner support reqular expression in web.regSaveParamJson?

in the following example wrong value is returned from the json request - looks like a bug

same json query was tested sucssfully using http://jsonpath.herokuapp.com/

web.regSaveParamJson(
        {
             paramName : 'ProductId_OverTheTop', 
             queryString : '$..steps[?(@.name =~ /.*Receivers and OTT/i)].displayableItems[?(@.name =~ /.*over the top/i)].productID', 
             scope : 'Body'
         }
    );

Thanks,
