Front-end label has to be inside its clipped Div

Hello, thanks for this great simple pluggin (without any Elementorish caterpilar).

In the back office preview the label SPAN.icv__label is INSIDE it’s clipped DIV.icv__wrapper
In the front office, it’s before. Then it’s not clipped as it’s shown in the backoffice.

Plus, once it will be inside, the label will need an extra style white-space:nowrap

Thanks in advance
