Description
Given the following Fluid code:
{variableWithNullValue -> f:format.html()}
throws the deprecation notice:
PHP Runtime Deprecation Notice: preg_split(): Passing null to parameter #2 ($subject) of type string is deprecated in /var/www/html/public/typo3/sysext/core/Classes/Html/HtmlParser.php line 60
Reason is in HtmlViewHelper where $renderChildrenClosure() returns null in this case and passes it further on until the notice is thrown in HtmlParser.
