Radio buttons not appearing in diff module

Code added to bulma.theme in commit 6933e0f places checkboxes/radio inside labels and unsets the 'children' context variable. Because of this the diff module was not displaying radio buttons. See the attached screenshots for reference.

I worked around this in my subtheme's form--element--radio template by using {{ element['#children'] }} rather than {{ children }}.

Perhaps having the checkbox/radio in the label is desired and this is not a bug; nonetheless I wanted to report the issue in case others encounter the problem and/or if it should be addressed in the module.
