Disable regex expressión using removeNeverAllowedRegex

[JSebastianOspina]

Hello everyone!

Im trying to disable this regex expressión, that is set in the _initNeverAllowedRefex method

            // src="js"
            'src\=(?<wrapper>[\'|"]).*\.js(?:\g{wrapper})' => $this->_replacement,

Im usign the removeNeverAllowedRegex method like this
$antixss->removeNeverAllowedRegex(['src\=(?<wrapper>[\'|"]).*\.js(?:\g{wrapper})']);

However, the regex expression is not beign removed. Could anyone tell what am I doing wrong?
Thank you !!
