TYPO3 Core

Hi,
when upgrading from 8.7.8 to 8.7.9 I get the following error:

In 8.7.8 my form was rendered to:

<label class="form-check-label check0">
<input class="xlarge form-check-input" type="radio" name="tx_form_formframework[anfrage][radiobutton-1]" value="Informatik" checked="checked">
<span> Informatik</span>
</label>

whereas in 8.7.9 and current 8.7 branch the result is an empty <span> tag:

<label class="form-check-label check0">
<input class="xlarge form-check-input" type="radio" name="tx_form_formframework[anfrage][radiobutton-1]" value="Informatik" checked="checked">
<span></span>
</label>

I could trace it down to changes in form -> Classes -> Service and ViewHelpers but could not break it down further to a single change. Check0 and counting the radiobuttons in the group is an extension of my own, which still works fine

Best regrads
