Control Wrap class missing

Hi there, I am testing a migrated site and after updating Contact Form 7 to the latest version I noticed some of the forms weren’t looking correct.

Prior to updating the control wrap looked like this:

<span class="wpcf7-form-control-wrap your-email">

It now looks like this:

<span class="wpcf7-form-control-wrap" data-name="your-email">

The class “your-email” is no longer there, so any styling that used this class isn’t working. Is there a way to tell ContactForm 7 to stop doing this?
